[PATCH] trivial: no "error" on preempt_count notice

The attached trivial patch simply changes the printk debug statement in
do_exit when preempt_count!=0 to say "note" instead of "error" and log
at KERN_INFO in lieu of KERN_ERR.

I want to keep the message around a bit, but people get too paranoid
when things like nfsd legitimately exit with a preempt_count=1.
