Change the WARN_ON to WARN_ON_NORT

Do we have a WARN_ON_NORT? I see a WARN_ON_NONRT, but not a
WARN_ON_NORT. Does this compile?

Sigh. Of course not. Reupdated patch (and yes this one compiles):

Thanks! Seems to have fixed the problem (of course!)
So far so good and nothing weird in the output of dmesg....

Oh well. Second time the machine hangs in two days in the same way (otherwise very stable running 3.18.x-rty)

(this is a bumblebee + bbswitch graphics laptop - argh, if I had known better...)
