fat: fix oops on corrupted vfat fs
a) don't bother with ->d_time for positives - we only check it for
negatives anyway.
b) make sure to set it at unlink and rmdir time - at *that* point
soon-to-be negative dentry matches then-current directory contents
c) don't go into renaming of old alias in vfat_lookup() unless it
has the same parent (which it will, unless we are seeing corrupted
image)
[hirofumi@mail.parknet.co.jp: make change minimum, don't call d_move() for dir]
