media: venus: hfi: fix the check to handle session buffer requirement
commit b18e36df upstream. Buffer requirement, for different buffer type, comes from video firmware. While copying these requirements, there is an OOB possibility when the payload from firmware is more than expected size. Fix the check to avoid the OOB possibility.
