usb: Stop reset procedure when a dev is handed over to a companion hcd

Browse Source 
Short circuit the retry loop in legacy_hub_port_reset() by returning an
error from usb_control_msg() when a device was handed over to a companion
by the ehci code. This avoids trying to reset low / fullspeed devices 5
times needlessly. Also do not print an error when a device has been handed
over.
