    wsp(4): Make evdev interface operational if sysmouse one is not opened
    
    Before this change evdev interface sent only copy of data sent through
    the sysmouse interface. It worked as /dev/wsp0 device node was
    automatcaly opened by devd(8) with starting of moused(8).
    Starting with 15.0 moused(8) does not open sysmouse interface by default
    thus making wsp(4) device dysfunctional.
    Fix it with adding extra checks of interfaces state.
