media: venus: hfi: fix the check to handle session buffer requirement
stable inclusion from stable-v6.6.3 commit db6bd4724356f4046f7b54dd4443cb272bfec6e8 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8LBQP Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=db6bd4724356f4046f7b54dd4443cb272bfec6e8 -------------------------------- commit b18e36dfd6c935da60a971310374f3dfec3c82e1 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.
