Hyunwoo Kim 9112bd1072 appletalk: Fix Use-After-Free in atalk_ioctl 
[ Upstream commit 189ff16722ee36ced4d2a2469d4ab65a8fee4198 ]

Because atalk_ioctl() accesses sk->sk_receive_queue
without holding a sk->sk_receive_queue.lock, it can
cause a race with atalk_recvmsg().
A use-after-free for skb occurs with the following flow.
```
atalk_ioctl() -> skb_peek()
atalk_recvmsg() -> skb_recv_datagram() -> skb_free_datagram()
```
Add sk->sk_receive_queue.lock to atalk_ioctl() to fix this issue.
