net: ethernet: ti: fix possible object reference leak
The call to of_get_child_by_name returns a node pointer with refcount
incremented thus it must be explicitly decremented after the last
usage.
Detected by coccinelle with the following warnings:
./drivers/net/ethernet/ti/netcp_ethss.c:3661:2-8: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 3654, but without a corresponding object release within this function.
./drivers/net/ethernet/ti/netcp_ethss.c:3665:2-8: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 3654, but without a corresponding object release within this function.
