sock_xmit() re-implements sigprocmask() and dequeue_signal_lock().

Yeah, that code was written before those existed. Thanks for the clean up.

Note: I can't understand this dequeue_signal(), it can dequeue SIGKILL
for the user-space task doing nbd_ioctl() ?

So we can interrupt an nbd transmission without waiting for a TCP timeout (when we know the network is down).
