smp: Add missing destroy_work_on_stack() call in smp_call_on_cpu()
For CONFIG_DEBUG_OBJECTS_WORK=y kernels sscs.work defined by
INIT_WORK_ONSTACK() is initialized by debug_object_init_on_stack() for
the debug check in __init_work() to work correctly.
But this lacks the counterpart to remove the tracked object from debug
objects again, which will cause a debug object warning once the stack is
freed.
Add the missing destroy_work_on_stack() invocation to cure that.
