ext2: avoid drop_nlink() during unlink of zero-nlink inode in ext2_unlink()
ext2_unlink() calls inode_dec_link_count() unconditionally, which
invokes drop_nlink(). If the inode was loaded from a corrupted disk
image with i_links_count == 0, drop_nlink()
triggers WARN_ON(inode->i_nlink == 0)
Follow the ext4 pattern from __ext4_unlink(): check i_nlink before
decrementing. If already zero, skip the decrement.
