[Mesa-stable] [PATCH v2 1/2] egl/wayland: use the destroy_window_callback for swrast

[Emil Velikov]

From: Emil Velikov <emil.velikov at collabora.com>

As described in commit 690ead4a135 ("egl/wayland-egl: Fix for segfault
in dri2_wl_destroy_surface.") if we attempt to destroy a EGL surface
attached to already destroyed Wayland window we'll get a segfault.

v2: set the correct callback alongside the window->private. (Dan)
