Remove bogons from the iSeries console

The iSeries driver calls into the n_tty ldisc code directly for some
bizarre reason. I previously tagged this with a query but this actually
does need fixing as n_tty methods when you have a different ldisc set are
not a good thing to call.

In n_tty mode this change should have no effect, the core tty layer has
always called the ldisc ioctl method *anyway* and will call the one for
the right ldisc.
