When attempting to transmit a packet, if the system fails to allocate
a mbuf, it may return without setting any timers.  If no more data is
scheduled to be transmitted (this was a FIN) the system will sit in
LAST_ACK state forever.

Thus, when mbuf allocation fails, set the retransmit timer if neither
the retransmit or persist timer is already pending.
