GPU Crash dump

Skylake GPU hang while using GStreamer in a WebRTC call.
It means GStreamer is simultaneously encoding and decoding VP8 (in 1080p) using
VAAPI. The hang occurs very quickly (less than 5 minutes) when the bandwidth is
limited and packets are lost.

Issue seems similar to #110394 but this time related to VP8.
Also it is very easy to reproduce (few minutes only).

Platform: x86_64
Kernel: 3.10.0-693.2.2.el7.x86_64
Linux distribution: CentOS 7.4

GStreamer version: 1.16.0
libva: commit 457470987cc9df5976ce8c72ffd4bfbd9baaf0f9
libva-intel-driver: commit f1d9ceddc0e84ed8d44dd59017b0e19b75dd5dcd
xf86-video-intel: commit 6f4972d5c368c30e971a23c1dc370d3e43761282

We are working on a way to dump and replay the network traffic to isolate this
issue and make it easily reproducible.
