Samples: iso_connected_benchmark: Use BT_LE_ADV_OPT_ONE_TIME

It is not intentional to continue advertising once a connection has been
established for two reasons:
 1. We do not configure enough connection contexts for this
 2. We don't want to generate controller scheduling conflicts that can
    possibly reduce performance.
