[SRU][Q/N/J:linux-azure][PATCH 1/1] scsi: storvsc: Process unsupported MODE_SENSE_10

[John Cabaj]

From: Long Li <longli at microsoft.com>

BugLink: https://bugs.launchpad.net/bugs/2139232

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")
