HID: output event in debugfs even if hid_get_report() fails
if hid_get_report() fails for whatever reason, the raw output of the report doesn't make it into 'events' file in debugfs at all, because we leave hid_input_report() too soon. We want the report to be always present for debugging reasons. Move the code around, so that the event makes it to 'events' file all the time, even if we are going to discard the report.
