The kernel would like to have all stack VLA usage removed[1]. Instead of dynamic allocation, just use XFRM_MAX_DEPTH as already done for the "class" array, but as per feedback, I will not drop maxclass because that changes the behavior. In one case, it'll do this loop up to 5, the other caller up to 6.
