hog: Fix stripping off read report bytes
If the HID subsystem requests a HID report to be read from the
device, we currently incorrectly strip off the first byte of the
response, if the device has report IDs set in the HID report
descriptor.
This is incorrect; unlike USB HID, the report ID is *not* included
in the HOG profile's HID reports, and instead exists out of band
in a descriptor on the report's bluetooth characteristic in the
device.
In this patch, we remove the erroneous stripping of the first
byte of the report, and (if report IDs are enabled) prepend the
report ID to the front of the result. This makes the HID report
returned indentical in format to that of a USB HID report, so
that the upper HID drivers can consume HOG device reports in the
same way as USB.
