Zach Brown dace60fc82 btrfs-progs: fix unaligned loads in receive
A user reported corruption after receiving subvolumes.  Turning up the
logging during the receive showed that the commands and string
attributes were being received correctly but the u64 attrbutes were
sometimes corrupted by having variable number of low order bytes
introduced.

It turned out they were on a platform that corrupts unaligned userspace
loads.  Loading the u64s from the unaligned pointers into the received
command stream with get_unaligned() fixed the problem.
