egl/wayland: Don't invalidate buffers on no-op resize
The Wayland platform's resize_callback is invoked from libwayland-egl
when wl_egl_window_resize() is called. The resize call is the only place
for the application to insert dx/dy arguments to wl_surface_attach().
When modifying the cursor hotspot (as in wayland/wayland#148), we want
to set dx/dy, but leave the surface size the same. If we get
wl_egl_window_resize() with the same width and height argument as we
already have, we do not need to invalidate our existing drawable.
