HID: validate HID report id size

HID: validate HID report id size

commit 43622021d2e2b82ea03d883926605bdd0525e1d1 upstream.

The "Report ID" field of a HID report is used to build indexes of
reports. The kernel's index of these is limited to 256 entries, so any
malicious device that sets a Report ID greater than 255 will trigger
memory corruption on the host:
