f2fs: Add sanity checks before unlinking and loading inodes
Add check for inode->i_nlink == 1 for directories during unlink,
as their value is decremented twice, which can trigger a warning in
drop_nlink. In such case mark the filesystem as corrupted and return
from the function call with the relevant failure return value.
Additionally add the check for i_nlink == 1 in
sanity_check_inode in order to detect on-disk corruption early.
