btrfs: btrfs_debug should consume fs_info when DEBUG is not defined
We can hit unused variable warnings when btrfs_debug and friends are
just aliases for no_printk. This is due to the fs_info not getting
consumed by the function call, which can happen if convenenience
variables are used. This patch adds a new btrfs_no_printk static inline
that consumes the convenience variable and does nothing else. It
silences the unused variable warning and has no impact on the generated
code:
$ size fs/btrfs/extent_io.o*
text data bss dec hex filename
44072 152 32 44256 ace0 fs/btrfs/extent_io.o.btrfs_no_printk
44072 152 32 44256 ace0 fs/btrfs/extent_io.o.no_printk
Fixes: 27a0dd61a5 (Btrfs: make btrfs_debug match pr_debug handling related to DEBUG)
