encoder: h264: Fix B frame encoding artifacts
The current implementation is updating the POC values only
in Slice parameter Buffer.But we are not filling the
picture order count and reference flags in VAPictureH264
while populating VA Picture/Slice structures.The latest
intel-vaapi-driver is directly accessing the above fields
from VAPicutreH264 provided as RefPicLists, which resulted
some wrong maths and prediction errors in driver.
