[ Upstream commit be693df3cf9dd113ff1d2c0d8150199efdba37f6 ]
The call to ehea_get_eth_dn 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/ibm/ehea/ehea_main.c:3163:2-8: ERROR: missing
of_node_put; acquired a node pointer with refcount incremented on line 3154,
but without a corresponding object release within this function.
