[Libva] [PATCH v4 intel-driver 08/11] render: don't deallocate surface storage of displayed frames.

[Gwenole Beauchesne]

Keep the VA surface storage live until it is explicitly scheduled
for destruction through vaDestroySurfaces() interface. Otherwise,
subsequent vaPutSurface() calls would have no effect.

This fixes various use cases like: display of interlaced frames
that are not marked for reference, multiple rendering to Pixmap
for EXT_texture_from_pixmap and more precisely interlaced streams.
