disk. That has a side effect of corrupting the "." entries names on
rename, since the call to createde() in the msdosfs_rename() sets the
de_Name to the target name. If any change to the directory attributes
is performed, the wrong name is written back to the on-disk direntry
on update.
Overwrite the de_Name for the directories on rename to correct the dot
name.
