The documentation of request_percpu_irq is confusing and suggest that the
interrupt is not enabled at all, while it is actually enabled on the local
CPU.

Clarify that.

You should submit this separately to the IRQ layer maintainers, rather
than try to include it in an unrelated set of changes targetting net-next.

Thanks.
