clockevents: Repair kernel-doc for clockevent_delta2ns()
Since the introduction of clockevents, i.e., commit
d316c57ff6bf
("clockevents: add core functionality"), there has been a mismatch between
the function and the kernel-doc comment for clockevent_delta2ns().
Hence, ./scripts/kernel-doc -none kernel/time/clockevents.c warns about it.
Adjust the kernel-doc comment for clockevent_delta2ns() for make W=1
happiness.
