Subject: [PATCH] ecore-wayland: Improve opaque setting logic.

1. Update win->region.opaque in ecore_wl_window_update_size, so that
the opaque info is synced with the geometry.

2. Add win->surface checking in ecore_wl_window_buffer_attach
before send any wl_surface related request, it will avoid segfault
in case that calling ecore_wl_window_buffer_attach() before
ecore_wl_window_show().
