HID: hid-sensor-hub: do not process feature reports in raw_event

In sensor_hub_raw_event(), feature reports are ignored but are still
marked as processed. This causes the in-kernel struct not to be
updated. Any non-updated fields in the feature reports are zero, and
they are being sent to the device. This causes confusion in the sensor
hub firmware, and some sensors are not powered up as a result.

This changes the raw_event rountine to only process input reports,
and let the hid core handle the incoming feature reports.
