Mark Thompson 2562dd9e78 vaapi_encode: Always reapply global parameters after the sequence header 
The codec sequence headers may contain fields which can overwrite the
fine parameters given in the specific settings (e.g. a crude bitrate
value vs. the max-rate / target-percentage / etc. values in
VAEncMiscParameterRateControl).  Always reapply all global parameters
after a sequence header to avoid this causing problems.
