[Libva] CBR encoding fails

[Artem Makhutov]

I forget to mention, that VBR encoding is also broken after this commit: "745340dd013399f64507de73401ab3adb712dad5 in intel-drivers (Encoding: Use the different delimeter to pass packed_rawdata and slice_header based on VAConfigAttribEncPackedHeaders attribute)".
