regulator: qcom_spmi: Fix warning Bad of_node_put()
For of_find_node_by_name(), you typically pass what the previous call returned. Therefore, of_find_node_by_name() increases the refcount of the returned node, and decreases the refcount of the node passed as the first argument. of_find_node_by_name() is incorrectly used, and produces a warning. Fix the warning by using the more suitable function of_get_child_by_name(). Also add a missing of_node_put() for the returned value, since this was previously being leaked.
