wayland: regression: use correct scaling factor when calling render_resize()

Browse source 
When an output property (such as scaling factor) has changed, we need
to call render_resize() to ensure the window surface is correct (for
example, we may have to change its scale).

The width/height parameters are in *logical* pixels (i.e. already
scaled). For render_resize() to work correctly when the scale is being
changed, it needs to be called with *current* logical size. This means
we need to scale our current width/height using the *old* scaling
factor.
