mgcp: log file and line of calls to handle_error()

When the FSM runs into an error condition handle_error() is called with
a cause code. The information about the error is then printed by handle_error(),
by this we do not get the sourcecode line of the location where the error
actually happend.

Convey the source code line number of the actual error in handle_error()
