    wayland/data-device: Do not unset focus on drag start
    
    On drag start, `data_device_start_drag()` issues a keyboard grab, which
    in turn will unset the current input focus.
    
    There is not need to unset the input focus in `data_device_start_drag()`
    as this is redone in `meta_wayland_keyboard_start_grab()`
