Commit783ddaebd3("staging: comedi: comedi_test: support scan_begin_src == TRIG_FOLLOW") neglected to add a test that `scan_begin_src` has only one bit set. The allowed values are `TRIG_FOLLOW` and `TRIG_TIMER`, but the code incorrectly also allows `TRIG_FOLLOW | TRIG_TIMER`. Add a call to `comedi_check_trigger_is_unique()` to check that only one trigger source bit is set.
