[PATCH] btrfs: make btrfs_compressed_bioset static

[Ben Dooks]

The 'btrfs_compressed_bioset' struct isn't exported outside of the
fs/btrfs/compression.c file, so make it static to fix the following
sparse warning:

fs/btrfs/compression.c:40:16: warning: symbol 'btrfs_compressed_bioset' was not declared. Should it be static?
