Update on this, it was a false positive.  It seems like the other crashes 
I was seeing were also caused by tracepoint 24, the fuzzer just found them 
via another code path I wasn't checking.

So from what I can tell the only troublesome tracepoint I've come across 
is the original irq_vectors/irq_work_exit problem.
