endpoint_fsm: add missing return in mgcp_pick_codec

The function mgcp_pick_codec is responsible to set the codec
information. In cases whee the codec type can not be determined
correctly it sets verb_info->codecs_len = 0, indicating to the caller
that no codocs are set. However, after that it does not return, it sets
an invalid codec anyway.

- Add missing return to keep the no-codec setting in case of error.
