vulkan/wsi/wayland: memset members of image to zero

struct wsi_wl_image is only used as member of the swapchain, and during
the swapchain creation the image is already initialized to zero. So we
have no problems with members of the image being used uninitialized.

But for consistency, memset the members of this struct to zero in
wsi_wl_image_init(). This can help to avoid problems in the future.
