This makes\nthe full-pass termination independent of the transport state while\npreserving the existing fallback selection semantics.\n\nAlso restore the NULL guard around the retran_path assignment. In the\nall-UNCONFIRMED case there is no eligible replacement transport, and\ninstalling NULL would leave later retransmit-path users and the debug\nprint with a NULL path."
