drivers: scsi: storvsc: Set srb_flags in all cases
commit f885fb73f64154690c2158e813de56363389ffec upstream.
Correctly set SRB flags for all valid I/O directions. Some IHV drivers on the
Windows host require this. The host validates the command and SRB flags
prior to passing the command down to native driver stack.
