powerpc/8xx: Fix possible device node reference leak
The call to of_find_compatible_node() returns a node pointer with
refcount incremented thus it must be explicitly decremented after the
last usage.
irq_domain_add_linear() also calls of_node_get() to increase refcount,
so irq_domain() will not be affected when it is released.
Detected by coccinelle.
Fixes: a8db8cf0d894 ("irq_domain: Replace irq_alloc_host() with revmap-specific initializers")
