usb: ohci: Do not resubmit and leak urbs for interrupt packets

The u-boot usb code uses polling for all endpoints, including interrupt
endpoints, so urbs should never be automatically resubmitted.

This also fixes a leak of the urb, as submit_int_msg() did not check if
an already re-submitted urb exists before creating a new one.
