Fix fat_update_time to fetch its own timestamp. It turns out that this is easily done by just passing a NULL timestamp pointer to fat_update_time. Also, it may be that things have changed by the time we get to calling fat_update_time after checking inode_needs_update_time. Ensure that we attempt the i_version bump if any of the S_* flags besides S_ATIME are set.
