soc: qcom: smsm: Fix refcount leak bugs in qcom_smsm_probe()

Browse source

[ Upstream commit af8f6f39b8 ]

There are two refcount leak bugs in qcom_smsm_probe():

(1) The 'local_node' is escaped out from for_each_child_of_node() as
the break of iteration, we should call of_node_put() for it in error
path or when it is not used anymore.
(2) The 'node' is escaped out from for_each_available_child_of_node()
as the 'goto', we should call of_node_put() for it in goto target.
