scsi: usb: uas: Do not query the IO Advice Hints Grouping mode page for USB/UAS 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 Advice Hints Grouping mode page
causes these devices to reset. Hence do not read the IO Advice Hints
Grouping mode page from USB/UAS storage devices.
