If a client indicates via CREATE_SESSION that no back channel
should be used on the existing connection, mark the client's
cl_cb_state DOWN instead of leaving it UNKNOWN.
Otherwise, a fresh session is created without an operational
backchannel, but the server never asserts SEQ4_STATUS_CB_PATH_DOWN.
