llc_sap_rcv was being preceded by skb_set_owner_r, then calling llc_state_process that calls sock_queue_rcv_skb, that in turn calls skb_set_owner_r again making the space allowed to be used by the socket to be leaked, making the socket to get stuck. Fix it by setting skb->sk at llc_sap_rcv and leave the accounting to be done only at sock_queue_rcv_skb.
