splice, net: Fix splice_to_socket() for O_NONBLOCK socket
LTP sendfile07 [1], which expects sendfile() to return EAGAIN when
transferring data from regular file to a "full" O_NONBLOCK socket,
started failing after commit 2dc334f1a63a ("splice, net: Use
sendmsg(MSG_SPLICE_PAGES) rather than ->sendpage()").
sendfile() no longer immediately returns, but now blocks.
Removed sock_sendpage() handled this case by setting a MSG_DONTWAIT
flag, fix new splice_to_socket() to do the same for O_NONBLOCK sockets.
