scsi: storvsc: Handle SRB status value 0x30

In response to a disk I/O request, Hyper-V has been observed to return SRB
status value 0x30.  This indicates the request was not processed by Hyper-V
because low memory conditions on the host caused an internal error.  The
0x30 status is not recognized by storvsc, so the I/O operation is not
flagged as an error. The request is treated as if it completed normally but
with zero data transferred, causing a flood of retries.

Add a definition for this SRB status value and handle it like other error
statuses from the Hyper-V host.
