xwayland: Recycle window buffers when setting pixmap 

Right now, we would recycle the window buffers whenever the window the
window is resized.

This, however, is not sufficient to guarantee that the buffers are up
to date, since changing the window border width for example would not
trigger a `WindowResize` (the border being outside the window).

Make sure we recycle the buffers on `SetWindowPixmap` to ensure that
the buffers will be recycled whenever the pixmap size is changed.
