[Libva] [PATCH v4 intel-driver 09/11] surface: drop SURFACE_DISPLAYED flag.

[Gwenole Beauchesne]

The optimization by which the VA surface storage is deallocated after
it is displayed and not used for reference or vaDeriveImage() purposes
cannot be implemented safely. We need to honour explicit lifetimes
defined by the upper codec layer.
