Fix a bug where kunit_run_irq_test() could hang if the system is too
slow. This was noticed with the crypto library tests in certain VMs.
Specifically, if kunit_irq_test_timer_func() and the associated hrtimer
code took over 5us to run, then the CPU would spend all its time
executing that code in hardirq context. As a result, the task executing
kunit_run_irq_test() never had a chance to run, exit the loop, and
cancel the timer.
To fix it, make kunit_irq_test_timer_func() increase the timer interval
when the other contexts aren't having a chance to run.
