009a2ba403Syzbot found a drop_nlink warning that is triggered by an easy to detect nlink corruption. This patch adds sanity checks to minix_unlink and minix_rename to prevent the warning and instead return EFSCORRUPTED to the caller. The changes were tested using the syzbot reproducer as well as local testing.
