res_pjsip_endpoint_identifier_user.c: * Fix copy/paste error in find_endpoint(). We were using a constant "anonymous" string instead of the passed in endpoint_name when checking the transport domain for an endpoint match. * Eliminate RAII_VAR in find_endpoint(). * Remove always true check in find_transport_state_in_use(). * Remove useless CMD_STOP in find_transport_state_in_use(). res_pjsip_endpoint_identifier_anonymous.c: * Eliminate RAII_VAR in anonymous_identify(). * Remove always true check in find_transport_state_in_use(). * Remove useless CMD_STOP in find_transport_state_in_use().
