    ledtrig-netdev: don't cancel work on events for different interfaces
    
    This fixes logic bug(in function netdev_trig_notify) introduced in
    0b2991a8ed32b5d9ba0a7c3441a72e1c1a1c4fde commit.
    Events triggered by different interfaces were stopping work queue so it
    wasn't working for tx/rx mode.
