TXs on the ibp_tx_queue are waiting for a connection to be
established. Failure to establish a connection could be due to a
problem with either the local NI or the remote NI, and o2iblnd cannot
currently distinguish between these failures. As such, it should
return LNET_MSG_STATUS_NETWORK_TIMEOUT to LNet so that LNet will
decrement the health value of both the local NI and the remote NI and
future sends can take these health values into account.
