[PATCH weston] libweston-desktop: Fix configure event for already well-sized surfaces

[Quentin Glidic]

From: Quentin Glidic <sardemff7+git at sardemff7.net>

Even if the surface size is already correct, we need to store the
configured size in case some other state change triggers a configure
event.
