fsck_msdosfs: reduce the scope of dentry deletion when dirent flags is ATTR_VOLUME

When dentry flag is ATTR_VOLUME because of 1 bit flip(from 0x10 to 0x18), removede function will delete all dentry from invalid dentry postion, so some normal dentries will be deleted in the same cluster.Unfortunately, these normal directories and files will not be visible to the user after wo do fsck_msdos

@OlCe2 can you take a look at this in light of your review of the ExFAT stuff maybe? if you have time...

Sorry, missed that. On discovering the title, I thought exactly the same as you... :-)

@bsdimp Sorry for the delayed reply.

The fsck_msdosd is a tool designed to repair corrupted vfat/fat/msdos filesystem, not exfat filesystem. This FreeBSD-derived tool is currently imported into the Android external/fsck_msdos repository.]

We recently identified a bug in this tool and are reaching out to request a fix.Thanks.
