rxrpc calls have a ring of packets that are awaiting ACK or retransmission and a parallel ring of annotations that tracks the state of those packets. If the initial transmission of a packet on the underlying UDP socket fails then the packet annotation is marked for resend - but the setting of this mark accidentally erases the last-packet mark also stored in the same annotation slot. If this happens, a call won't switch out of the Tx phase when all the packets have been transmitted. Fix this by retaining the last-packet mark and only altering the packet state.
