[PATCH weston] simple-egl: Reset opaque region if not fullscreen.

[Scott Moreau]

If simple-egl is toggled fullscreen, the opqaue region is set for the surface
but never removed after exiting fullscreen. This patch resets the opaque region
to 0 if the surface is not fullscreen and -o was not passed. This fixes the
problem introduced sometime since 6a615d2621, when this was last fixed.

I noticed this was broken again. This patch resets the opaque region after
fullscreen toggle so the surface is restored to its original alpha.
