usbd: clear endpoint busy/claimed when a completion event is dropped
An XFER_COMPLETE dropped by a full event queue leaves its endpoint's
BUSY|CLAIMED state set forever - the consumer that normally clears it
never sees the event, so usbd_edpt_claim()/usbd_edpt_xfer() fail from
then on and the class never re-arms the endpoint. Clear both flags when
the enqueue fails: the completion is lost either way, but the endpoint
stays usable.
Unit test: arm a bulk endpoint, drop its completion against a full
queue, verify the endpoint can be claimed and re-armed.
