media: venus: hfi: fix the check to handle session buffer requirement
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.
