of/irq: Fix remaining refcount leaks in of_irq_init()

Browse Source 
Successfully initialized controllers are moved to intc_parent_list,
but the final cleanup only frees the descriptors. The device node
references taken with of_node_get() and the interrupt parent
references are therefore leaked on the normal return path. Drop both
before kfree(), as the intc_desc_list cleanup already does.
