Patch "irq-tracer-fix.patch" from the additions at rt13 of the
26 preempt_rt patch set introduced a test on action->flags, but it
comes at the end of a loop where we will have run all the
chained handlers until action==NULL. Since we have stored the
action->flags (or'd) in status while walking the action chain,
use status in the check instead.
