Description
sd currently issues MODE SENSE for page codes 3 and 4 which have been dropped from SBC-3 (the T10 standard for direct-attached block devices), resulting in illegal requests. There are also cases where we may erroneously assume a block device is SBC-3 compliant if it reports SPC-4 compliance.

Current SBC-2 specs also removed these mode pages.

With #7811 resolved, we don't send the MODE SENSE for pages 3 and 4. Anything else to do here?
