powerpc/xive: Fix refcount leak in xive_get_max_prio
of_find_node_by_path() returns a node pointer with
refcount incremented, we should use of_node_put() on it when done.
Add missing of_node_put() to avoid refcount leak.
Fixes: eac1e731b59e ("powerpc/xive: guest exploitation of the XIVE interrupt controller")
