Input: kbtab - simplify kbtab_disconnect()
There is no need to check whether kbtab structure is attached to the interface; if it isn't and we are called we have much bigger problems. Also no need to call usb_kill_urb() in kbtab_disconnect() since it is being called in kbtab_close(). Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
