[PATCH] kunit: irq: Unregister on-stack timer and work from debugobjects

[Eric Biggers]

In kunit_run_irq_test(), call destroy_hrtimer_on_stack() and
destroy_work_on_stack() to unregister the hrtimer and work from the
debugobjects infrastructure (when CONFIG_DEBUG_OBJECTS_TIMERS=y and
CONFIG_DEBUG_OBJECTS_WORK=y) before the function returns.

Found via code review; the lack of the unregistrations didn't actually
cause a warning, since the objects are inactive upon return anyway.  But
they should be there, otherwise debugobjects keeps tracking the objects.

Fixes: 950a81224e8b ("lib/crypto: tests: Add hash-test-template.h and gen-hash-testvecs.py")
