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

commit 844817e47eef14141cf59b8d5ac08dd11c0a9189 upstream.

The report passed to us from transport driver could potentially be
arbitrarily large, therefore we better sanity-check it so that raw_data
that we hold in picolcd_pending structure are always kept within proper
bounds.
