fhandler_tty_slave::ioctl (FIONBIO) return status

[Brian Ford]

I don't really understand the code here in depth, but could someone
explain to me why the attached trivial patch would'nt fix a minor bug?
Thanks.

        * fhandler_tty.c (fhandler_tty_slave::ioctl): Assure correct
        return value for FIONBIO.
