regulator: of: regulator_of_get_init_data() missing of_node_get() 

Boot fails for qcom-apq8074-dragonboard on 4.13-rc1 with error:
OF: ERROR: Bad of_node_put() on /soc/spmi@fc4cf000/pm8941@1/regulators

The error will occur if the configuration is set to:
   CONFIG_OF_OVERLAY y
   CONFIG_OF_UNITTEST y
   CONFIG_OF_DYNAMIC y
   CONFIG_OF_RESOLVE y

If CONFIG_OF_DYNAMIC is enabled then of_node_release() detects an
attempt to release a node that is still attached to the device tree.
