[PATCH i-g-t 3/4] lib/igt_draw: Ensure drawing is complete when draw_rect_render returns

[Jouni Högander]

Currently draw_rect_render is not ensuring drawing is complete when
it returns. This may lead e.g. crc mismatches if crc is taken too
early after starting the drawing. Fix this by calling intel_bb_sync
before return.
