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

Browse source

commit b18e36dfd6 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.
