usb: core: usb_submit_urb: downgrade type check
Checking for the endpoint type is no reason for a WARN, as that can
cause a reboot. A driver not checking the endpoint type must not cause a
reboot, as there is just no point in this. We cannot prevent a device
from doing something incorrect as a reaction to a transfer. Hence
warning for a mere assumption being wrong is not sensible.
