cosmetic: mgcp_client_fsm: change error message.

The error message: "abrupt FSM termination with connections still
present, sending unconditional DLCX..." implies a more serious problem
than in actually is. Even when connections are present on the
mgcp_client_fsm while it terminates, normal operation is still possible.
Lets change the loglevel to NOTICE and remove the "aprupt" from the
phrase.
