The commit f9b2ee714c5c ("SUNRPC: Move UDP receive data path into a workqueue context"), as a side effect, moved the skb_free_datagram() call outside the scope of the related socket lock, but UDP sockets require such lock to be held for proper memory accounting. Fix it by replacing skb_free_datagram() with skb_free_datagram_locked().
