powerpc: Fix irq_alloc_host() reference counting and callers

Browse Source 
When I changed irq_alloc_host() to take an of_node
(52964f87c6: "Add an optional
device_node pointer to the irq_host"), I botched the reference
counting semantics.

Stephen pointed out that it's irq_alloc_host()'s business if
it needs to take an additional reference to the device_node,
the caller shouldn't need to care.
