egl-x11: Fix a crash when the app has non-Cogl windows

Browse Source 
The handler for ConfigureNotify events in the EGL X11 winsys was
incorrectly trying dereference the onscreen pointer even if it didn't
find an onscreen for the X window that has resized. This meant that if
the application has other windows that weren't created by Cogl then it
would crash when handling events for them.
