Invalid buffer ids are defined by VA_INVALID_ID. Use that through out vaapi_*.c support files now that we have private data initialized and managed by libavcodec. Previously, the only requirement for the public vaapi_context struct was to be zero-initialized. This fixes support for 3rdparty VA drivers that strictly conform to the API whereby an invalid buffer id is VA_INVALID_ID and the first valid buffer id can actually be zero.
