hog: Fix checking for Report ID item presence Report ID item in Report Descriptor is now detected by simply looking for applicable item prefixes anywhere in data and does not take items structure into consideration. This could lead to false-positive detections in case value we look for is just part of item data, not an actual item prefix. As defined in Device Class Definition for HID (6.2.2.7), Report ID is a short item with prefix 100001nn (binary) thus we do not need to do complete parsing of Report Descriptor but only need to check items prefixes in order to find Report ID items reliably. This patch checks Report Descriptor item by item looking for item prefix which matches Report ID, as defined in spec above.
