[PATCH V2 1/1] scsi: storvsc: Set the SRB flags correctly when no data transfer is needed

From: K. Y. Srinivasan
Date: Fri May 01 2015 - 12:44:00 EST


Set the SRB flags correctly when there is no data transfer. Without this change
some IHV drivers will fail valid commands such as TEST_UNIT_READY.
