IRP IoStatus.Status and handler returned status should always match.

When the guts of the handler for IRP_MN_QUERY_RESOURCE_REQUIREMENTS were
ripped out the remaining code unconditionally returned STATUS_SUCCESS whilst
the IRP was almost certainly preloaded with STATUS_NOT_SUPPORTED. To fix,
simply stop handling that IRP and the dispatcher default clause DTRT.
