From: Zijun Hu <quic_zijuhu@quicinc.com>

In irq_of_parse_and_map(), refcount of device node @oirq.np was got
by successful of_irq_parse_one() invocation, but it does not put the
refcount before return, so causes @oirq.np refcount leakage.

Fix by putting @oirq.np refcount before return.

Fixes: e3873444990d ("of/irq: Move irq_of_parse_and_map() to common code")
