Subject: [PATCH] 90dm: fixup dependency cycle between MD and DM shutdown

DM devices might be located on top of MD devices, so we need to
call the DM shutdown script before MD shutdown. The exception
here are multipath devices, which are below MD devices.
So skip removing multipath devices here to avoid spurious errors.
