of/irq: Fix device node refcount leakages in of_irq_count()
commit bbf71f44aaf241d853759a71de7e7ebcdb89be3d upstream.
of_irq_count() invokes of_irq_parse_one() to count IRQs, and successful
invocation of the later will get device node @irq.np refcount, but the
former does not put the refcount before next iteration invocation, hence
causes device node refcount leakages.
Fix by putting @irq.np refcount before the next iteration invocation.
