Draft: handle h264 decoding crashing amdgpu case

Ruijing Dong requested to merge rdong/mesa-rdong-2021:validate_target_buffer_id into main

What does this MR do and why?

There are some effects from the error streams.

  1. Application could send NULL buffer as target buffer, which should be checked.
  2. In error case, the bitstream is corrupted, and which could access some invalid context info and location, which causes amdgpu crashing. There is no good way handling this one, now trying to increase h264 context buffer to the max, in 1080p level 4.2 case, it will increase 18M space.
