mm/damon: document damon_call_control->dealloc_on_cancel repeat behavior

damon_call_control->dealloc_on_cancel works only when ->repeat is true.
But the behavior is not clearly documented. DAMON API callers can
understand the behavior only after reading kdamond_call() code. Document
the behavior on the kernel-doc comment of damon_call_control.
