input: virtio: don't send mouse wheel event twice
On Linux, a mouse event is generated for both down and up when mouse
wheel is used. This caused virtio_input_send() to be called twice each
time the wheel was used.
This commit adds a check for the button down state and only calls
virtio_input_send() when it is true.
