powerpc: Fix irq_alloc_host() reference counting and callers
When I changed irq_alloc_host() to take an of_node (52964f87c64e6c6ea671b5bf3030fb1494090a48: "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.
