[Libva] [libva][PATCH v3 1/6] vpp: fix memory leak in DNDI code path.

[Xiang, Haihao]

From: Gwenole Beauchesne <gb.devel at gmail.com>

The original current_out_surface was never released on exit. Main
reason for that is the legacy VPP framework that did not allow the
VADriverContextP handle to be passed down to the desired .finalize()
hook. Improved that to bring it on par with the VEBOX code path.
