scsi: storvsc: Process unsupported MODE_SENSE_10

commit 9eacec5d18f98f89be520eeeef4b377acee3e4b8 upstream.

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.
