unix_stream_read_skb() checks SOCK_DEAD only when the dequeued skb is OOB skb. unix_stream_read_skb() is called for a SOCK_STREAM socket in SOCKMAP when data is sent to it. The function is invoked via sk_psock_verdict_data_ready(), which is set to sk->sk_data_ready(). During sendmsg(), we check if the receiver has SOCK_DEAD, so there is no point in checking it again later in ->read_skb(). Also, unix_read_skb() for SOCK_DGRAM does not have the test either. Let's remove the SOCK_DEAD test in unix_stream_read_skb().
