[PATCH] drm/amdgpu: Avoid possibly uninitialized variable

[Thierry Reding]

From: Thierry Reding <treding at nvidia.com>

The min_ctx_size is only initialized for H265, so garbage will end up in
buf_sizes[4] for all other stream types. Better initialize the value to
0 to avoid unpleasant surprises.
