Fixes gcc '-Wunused-but-set-variable' warning:

fs/btrfs/compression.c: In function 'end_compressed_bio_write':
fs/btrfs/compression.c:232:25: warning:
 variable 'tree' set but not used [-Wunused-but-set-variable]

It not used any more after
commit 2922040236f9 ("btrfs: Remove extent_io_ops::writepage_end_io_hook")
