Andrea Parri (Microsoft) ab548fd21e scsi: storvsc: Fix max_outstanding_req_per_channel for Win8 and newer 
Current code overestimates the value of max_outstanding_req_per_channel for
Win8 and newer hosts, since vmscsi_size_delta is set to the initial value
of sizeof(vmscsi_win8_extension) rather than zero.  This may lead to wrong
decisions when using ring_avail_percent_lowater equals to zero.  The
estimate of max_outstanding_req_per_channel is 'exact' for Win7 and older
hosts.  A better choice, keeping the algorithm for the estimation simple,
is to err the other way around, i.e., to underestimate for Win7 and older
but to use the exact value for Win8 and newer.
