Prepare to track skb metadata location independently of MAC header offset. Following changes will make skb_metadata_set() record where metadata ends relative to skb->head. Hence the helper must be called when skb->data already points past the metadata area. Adjust the driver to pull from skb->data before calling skb_metadata_set().
