Suppport for exposing hidden raid components for sg interface. The sdev->no_uld_attach flag will set set accordingly. The sas module supports adding/removing raid volumes using online storage management application interface. This patch rely's on patch's provided to me by Christoph Hellwig, that exports device_reprobe. I will post those patch's on behalf of Christoph.
