dwc_otg: only do_split when we actually need to do a split

The previous test would fail if the root port was in fullspeed mode
and there was a hub between the FS device and the root port. While
the transfer worked, the schedule mangling performed for high-speed
split transfers would break leading to an 8ms polling interval.
