thermal/drivers/imx_sc: Add missing of_node_put for loop iteration
Early exits from for_each_available_child_of_node() should decrement the
node reference counter.  Reported by Coccinelle:

  drivers/thermal/imx_sc_thermal.c:93:1-33: WARNING:
    Function "for_each_available_child_of_node" should have of_node_put() before return around line 97.
