af_unix: Don't check SOCK_DEAD in unix_stream_read_skb().
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().
