thermal/drivers/sprd: 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/sprd_thermal.c:387:1-23: WARNING:
Function "for_each_child_of_node" should have of_node_put() before goto around lines 391.
