criu_checkpoint_events() allocates the ev_privs[] array, sized by the runtime count returned from kfd_get_num_events(), using the open-coded kvzalloc(n * sizeof(*p), ...) form. Switch to kvcalloc(), which carries the same zero-on-allocation semantics and adds the standard size_mul overflow check on the n * sizeof multiplication.
