LU-17270 kfilnd: Check status of TAG_RX_OK in WAIT_COMP

When the target of a bulk Get/Put drops the message it sends
ENODATA back to the initiator via immediate data. This status needs to
be accounted for while the transaction is in the TN_STATE_WAIT_COMP
state, otherwise it can be lost if the TN_EVENT_TAG_RX_OK event
arrives before the TN_EVENT_TX_OK event.
