[PATCH] Set the DE_UPDATE flag on the directory node on msdosfs

[Kevin Lo]

If you try to NFS export a fat32 formatted external usb devices, 
you'll notice if a new file is created, you won't see that file 
on the NFS client. The reason is msdosfs(5) doesn't change the 
modify time of the directory when an entry is created.

Attached is a patch against HEAD that sets DE_UPDATE on the 
directory node in both createde() and removede(). 
Please test it, thanks.
