br_allowed_ingress() has two problems. 1. If br_allowed_ingress() is called by br_handle_frame_finish() and vlan_untag() in br_allowed_ingress() fails, skb will be freed by both vlan_untag() and br_handle_frame_finish(). 2. If br_allowed_ingress() is called by br_dev_xmit() and br_allowed_ingress() fails, the skb will not be freed. Fix these two problems by freeing the skb in br_allowed_ingress() if it fails.
