HID: hidraw: fix hidraw_disconnect() 

hidraw_disconnect() first sets an entry in hidraw_table to NULL
and calls device_destroy() afterwards. The thereby called
hidraw_release() tries to read this already cleared value resulting
in never removing any device from the list.
This got fixed by changing the order of events.
