switch AF_UNIX to generic_file_splice_read() The only obstacle to using generic_file_splice_read() in there is that we need an equivalent of MSG_DONTWAIT with SPLICE_F_NONBLOCK in splice flags. Introduce IOCB_NDELAY, make sock_read_iter() honour it (and generic_file_splice_read() set it when SPLICE_F_NONBLOCK is present) and generic_file_splice_read() for AF_UNIX sockets will do the right thing.
