usb: ehci: Use endpoint in URB to get maxpacket

usb_maxpacket() looks up the endpoint number in the pipe which can fail
if the interface or configuration changes before the routine is called.
This is unexpected and may even cause a modulo by zero afterwards.

So use usb_endpoint_maxp() routine which uses the endpoint stored in URB
to get the maxpacket.
