video: rockchip: vop: 3399: fix post empty when enable afbdc after resume

userspace will set several frame after vop suspend, so the kernel back
buffer will be freed and after resume vop will read a freed buffer and lead
to post empty, so we close all win before suspend, after resume vop will
display black until userspace set a new frame.
