HID: magicmouse: sanity check report size in raw_event() callback

commit c54def7bd64d7c0b6993336abcffb8444795bf38 upstream.

The report passed to us from transport driver could potentially be
arbitrarily large, therefore we better sanity-check it so that
magicmouse_emit_touch() gets only valid values of raw_id.
