rt2x00: Fix chipset detection for rt2500usb
The commit below changed the semantics of rt2x00_check_rev so that it no
longer checked the bottom 4 bits of the rev were non-zero. During that
conversion this part of the check was not propogated to the rt2500usb
initialisation.

rt2x00: Simplify rt2x00_check_rev
Without this check rt73 devices are miss recognised as rt2500 devices and
two drivers are loaded. Preventing the device being used. Reinstate this
check.
