mount_devfs - don't unconditionally clear rules

* mount_devfs was unconditionally clearing all rules of a mountpoint
  after mounting.

* According to the man page (and my original intentions, I'd presume),
  mount_devfs should only clear the rules of a mountpoint if it was
  already mounted. So fix mount_devfs accordingly.
