fix handling of loopback drives

Ok, just found the problem.  It only happens in a specific situation.  To
reproduce (in this example with drive D:, mapped to /media/cdrom0):

  sudo mount image.iso /media/cdrom0 -o loop
  mv image.iso image2.iso

at this point, wine will be incapable of volume access on D:, because the code
in ntdll/directory.c:parse_mount_entries() contains a sanity check to require
that image.iso is a regular file.  However, image.iso may not even exist!

Attached patch fixes this by allowing either the file to exist and be a regular
file, or not exist at all (as long as its loopback device exists, of course).

(Note: This fix has nothing to do with supporting this on C: or PhysicalDrive:.
 Besides, I don't think there's much point in trying to support those since
chances are they're rarely used)
