This commit works-around a serious issue when running with the RPi backend.
When an EGL client shuts down and destroys it's EGL window, Weston dies with
a segmentation fault in the above function (because `buffer` is now NULL).
The addition of a simple NULL check avoids the problem.
This is a minor re-formatting of the patch already submitted here:
