[PATCH] scsi: storvsc: Process unsupported MODE_SENSE_10

From: Long Li <longli@microsoft.com>

The Hyper-V host does not support MODE_SENSE_10 and MODE_SENSE.
The driver handles MODE_SENSE as unsupported command, but not for
MODE_SENSE_10. Add MODE_SENSE_10 to the same handling logic and
return correct code to SCSI layer.

Fixes: 89ae7d709357 ("Staging: hv: storvsc: Move the storage driver out of the staging area")
