[Libva] [PATCH Libva-intel-driver V2 4/6] H264_encoding: Reset the last_packed_header_type to avoid the unpaired packed header type/data

[Zhao, Yakui]

From: "Zhao, Yakui" <yakui.z...@intel.com>

After adding the support of inserting the packed rawdata, more group of packed 
header data
can be passed. In order to insert the packed rawdata correctly, the packed 
header type/
data should be paired.
