scsi: storvsc: Handle additional SRB status values

Testing of virtual Fibre Channel devices under Hyper-V has shown additional
SRB status values being returned for various error cases.  Because these
SRB status values are not recognized by storvsc, the I/O operations are not
flagged as an error. Requests are treated as if they completed normally but
with zero data transferred, which can cause a flood of retries.

Add definitions for these SRB status values and handle them like other
error statuses from the Hyper-V host.
