RDMA/nes: Fix Xansation test crash on cm_node ref_count

While running a Xansation test, an active side node crashed.  The
problem started on the passive side, which generated an STtag that was
0.  The passive side sent a TERMINATE instead of an MPA REJECT msg.
The active side, receives TERMINATE and sends connect_err() and set
the cm_node state to CLOSED.  The passive side sends FIN + ACK after
TERMINATE.  Active side ends up in handle_ack_pkt() and send_reset().
send_reset() consumes 1 cm_node's ref_count.  Because the cm_node is
in CLOSED state, which means that cm_node will be destroyed after
completion of the connect_err() indication, CM will crash after
send_reset().
