btrfs: remove the inode cache check at btrfs_is_free_space_inode()
The inode cache feature was removed in kernel 5.11, and we no longer have
any code that reads from or writes to inode caches. We may still mount a
filesystem that has inode caches, but they are ignored.
Remove the check for an inode cache from btrfs_is_free_space_inode(),
since we no longer have code to trigger reads from an inode cache or
writes to an inode cache. The check at send.c is still needed, because
in case we find a filesystem with an inode cache, we must ignore it.
Also leave the checks at tree-checker.c, as they are sanity checks.
This eliminates a dead branch and reduces the amount of code since it's
in an inline function.
Before:
$ size fs/btrfs/btrfs.ko
text data bss dec hex filename

After:
$ size fs/btrfs/btrfs.ko
text data bss dec hex filename
1620502 189240 29032 1838774 1c0eb6 fs/btrfs/btrfs.ko
