[PATCH] usb: core: usb_submit_urb: downgrade type check

[Oliver Neukum <oneukum@suse.com>]

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.
