Title:
  double free in mir egl display when calling eglTerminate and
  gbm_device_destroy

Bug description:
  In my standalone Xmir I do the following things:

  /* Init code */
  if (xmir_screen->gbm) /* NULL on !mesa */
      mir_connection_drm_set_gbm_device(xmir_screen->conn, xmir_screen->gbm);

  xmir_screen->egl_display =
  eglGetDisplay(mir_connection_get_egl_native_display(xmir_screen->conn));

  /* Shutdown code */
      eglTerminate(xmir_screen->egl_display);

      if (xmir_screen->gbm)
          gbm_device_destroy(xmir_screen->gbm);

  This works as expected when gbm is NULL, but I'm getting a double free in gbm_device_destroy with the eglTerminate.
  Calling eglGetDisplay(xmir_screen->gbm) instead works as expected.
