Fixed optimization error in the HID Parser item value USB_SetHIDReportItemInfo() and USB_GetHIDReportItemInfo() routines if the report item was NULL (which should be allowable according to the API).

Fixed HID Parser CALLBACK_HIDParser_FilterHIDReportItem() callback function not being passed a cacheable report item pointer.
