input/keyboard: don't send key release if we don't have focused surface

"The compositor must not send this event if the wl_keyboard did not
have an active surface immediately before this event. The compositor
must not send this event if state is pressed (resp. released) and the
key was already logically down (resp. was not logically down)
immediately before this event."
