  [Hyper-V] storvsc: Set the SRB flags correctly when no data transfer

Bug description:
  The following critical bugfix has been accepted into the upstream
  kernel. It is needed for 15.10, 15.02, 14.10, 14.04 and 14.04 HWE
  (and, by extension, 12.04 and 12.04 HWE). We have seen IHV drivers in
  the field throw errors and time out due to receiving SRB flags set
  when no data transfer is expected.

  storvsc: Set the SRB flags correctly when no data transfer is needed
  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.
