The original intent of the LNET_MSG_STATUS_NETWORK_TIMEOUT health
status was to handle cases where the LND was unsure whether the
failure was due to the local or remote NI. In this case, we'll want
to decrement both the local and remote NI health and allow recovery
to ascertain which interface is actually healthy.
