of: fix "/cpus" reference leak in of_numa_parse_cpu_nodes()



The call to of_find_node_by_path("/cpus") returns the cpus device_node
with its reference count incremented. There is no matching of_node_put()
call in of_numa_parse_cpu_nodes() which results in a leaked reference
to the "/cpus" node.

This patch adds an of_node_put() to release the reference.
