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

[Zhao, Yakui]

From: "Zhao, Yakui" <yakui.zhao at 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.
