egl: Check for NULL native_window in eglCreateWindowSurface
We have customers using NULL as a way to test the robustness of the API. Without this check, EGL will segfault trying to dereference dri2_surf->wl_win->private because wl_win is NULL. This fix adds a check and sets EGL_BAD_NATIVE_WINDOW v2: Incorporated feedback from idr - moved the check to a higher level function.
