[v2,2/2] scsi: core: Do not query IO hints for USB devices

Recently it was reported that the following USB storage devices are unusable
with Linux kernel 6.9:
* Kingston DataTraveler G2
* Garmin FR35

This is because attempting to read the IO hint VPD page causes these devices
to reset. Hence do not read the IO hint VPD page from USB storage devices.

I have commented on v1, same applicable here. Not that it's a big deal
for this change, but in general can you follow the advice given there?
