usb-storage should depend on SCSI rather than forcing SCSI to be
enabled.

Using 'select' is all very well for the case where the target
configuration symbol is not user selectable, but in the case that
it is, it leads to the confusion shown above.

Maybe USB_STORAGE help text should say that it needs SCSI support?

Therefore, I propose this patch:
