evas gl_x11: Fix uninitialized use of re in eng_output_flush()

In case of render_mode == EVAS_RENDER_MODE_ASYNC_INIT we're jumping
directly to end which then calls
evas_gl_preload_render_unlock(eng_preload_make_current, re);

Make sure re is initialized with the render engine data so we don't
dereference junk.
