People have been complaining that the latest 3.12-rt does not boot on
intel i7 boxes. And by reverting this patch, it boots fine.

I happen to have a i7 box to test on, and sure enough, the latest
3.12-rt locks up on boot and reverting the
timers-do-not-raise-softirq-unconditionally.patch, it boots fine.

Looking into it, I made this small update, and the box boots. Seems
checking "active_timers" is not enough to skip raising softirqs. I
haven't looked at why yet, but I would like others to test this patch

I'll leave why this lets i7 boxes boot as an exercise for Thomas ;-)
