net: remove dead code after sk_data_ready change
As a followup to commit 676d23690fb ("net: Fix use after free by removing length arg from sk_data_ready callbacks"), we can remove some useless code in sock_queue_rcv_skb() and rxrpc_queue_rcv_skb() Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.
