When interacting with SW elements, the buffers and underlying video
memory could be mapped as read/write. However, we need to use those
buffers again as plain VA surfaces, we have to make sure the VA image
is thus committed back to VA surface memory.
This fixes pipelines involving avdec_* and vaapi{postproc,sink}.
