of/irq: Fix device node refcount leakage in API of_irq_parse_raw()
if the node @out_irq->np got by of_irq_parse_raw() is a combo node which
consists of both controller and nexus, namely, of_irq_parse_raw() returns
due to condition (@ipar == @newpar), then the node's refcount was increased
twice, hence causes refcount leakage.
Fix by putting @out_irq->np refcount before returning due to the condition.
Also add comments about refcount of node @out_irq->np got by the API.
Fixes: 041284181226 ("of/irq: Allow matching of an interrupt-map local to an interrupt controller")
