[SRU][Vivid][Wily][PATCH 1/1] storvsc: Set the SRB flags correctly when no data transfer is needed

[Joseph Salisbury]

From: "K. Y. Srinivasan" <kys at microsoft.com>

BugLink: http://bugs.launchpad.net/bugs/1439780

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.
