btrfs-progs: ins: dump-tree: Print tree name for extent data/tree block backref 

Print tree name instead of number to make output more readable.

Example:
[before]
   extent data backref root 5 objectid 257 offset 16384 count 1

   tree block backref root 18446744073709551607

[after]
   extent data backref root FS_TREE objectid 257 offset 16384 count 1

   tree block backref root DATA_RELOC_TREE
