hid: bigben_probe(): validate report count

bigben_probe() does not validate that the output report has the
needed report values in the first field.
A malicious device registering a report with one field and a single
value causes an head OOB write in bigben_worker() when
accessing report_field->value[1] to report_field->value[7].
Use hid_validate_values() which takes care of all the needed checks.
