Since the commmit 8dd3e5dc2d
("btrfs-progs: tests: fix misc-tests/029 to run on NFS") added the
compatibility of NFS, it called run_mayfail() in the last of the test.
However, run_mayfail() always return the original code. If the test
case is not running on NFS, the last `run_mayfail rmdir "$SUBVOL_MNT"`
will fail with return value 1 then the test fails:
================================================================
====== RUN MAYFAIL rmdir btrfs-progs/tests/misc-tests/029-send-p-different-mountpoints/subvol_mnt
rmdir: failed to remove 'btrfs-progs/tests/misc-tests/029-send-p-different-mountpoints/subvol_mnt': No such file or director
failed (ignored, ret=1): rmdir btrfs-progs/tests/misc-tests/029-send-p-different-mountpoints/subvol_mnt
test failed for case 029-send-p-different-mountpoints
=================================================================
Every instrument in this script handles its error well, so do exit 0
manually in the last.

The directories created under default path needs a fallback in case it's
on NFS and root cannot create the directory. Update the test to create
only one additional mount point and use the TEST_MNT as the toplevel
one.
The error message we're looking for is now a bit weaker due to the less

The runtime of the test is over 4 minutes when hosted on NFS, the
fallocate phase takes the most time. As fallocate can't take multiple
arguments, we can't save the overhead by creating the files at once.
Create the files in batches in the background, this improves the runtime
to 2 minutes.

Now two locations can detect such problem, either by device item
used/total bytes check, or by early dev extents check against device
boundary.
The image is hand-crafted image which uses DATA SINGLE chunk to feed
btrfs check. As expected, as long as block group item, chunk item,
device used bytes match, older versions check can't detect such problem.

Test case misc/021 is testing if we could mount a single disk btrfs
image recovered from multi disk fs.
The problem is, current kernel has extra check for block group, chunk
and dev extent. This means no image can pass btrfs check for chunk
tree and the filesystem will not mount.
So do extra btrfs check before mount, this will also help us to locate
the problem in btrfs-image easier.

For trees have been balanced, leaves are with flag BTRFS_HEADER_FLAG_RELOC and
extent data backrefs are shared. Like:
=====================
item 0 key (11927552 EXTENT_ITEM 524288) itemoff 3932 itemsize 63
refs 129 gen 7 flags DATA
shared data backref parent 35897344 count 41
shared data backref parent 35426304 count 37
shared data backref parent 35422208 count 51
=====================
Then make the leaf which owns the extent data cowed. The shared data
backref was to transferred to keyed data ref, but remaining backrefs are
still shared. Like:
=====================
item 0 key (11927552 EXTENT_ITEM 524288) itemoff 3887 itemsize 108
refs 129 gen 7 flags DATA
extent data backref root 5 objectid 258 offset 0 count 40
extent data backref root 5 objectid 257 offset 0 count 1
shared data backref parent 35426304 count 37
shared data backref parent 35422208 count 51
=====================
However lowmem mode used to iterate the whole inode to find all
references, and doesn't care if a reference is already counted by the
shared tree block.
