drm/amdgpu: fix division by zero with invalid uvd dimensions
When width or height is less than 16, width_in_mb or height_in_mb
becomes 0, leading to fs_in_mb being 0. This causes a division by
zero when calculating num_dpb_buffer in H264 and H264 Perf decode
paths.
Add validation to reject frames with width < 16 or height < 16
before performing any calculations that depend on these values.
V2: Format change - move up all vaiable definitions.
V3: Use warn_once to avoid spam.
