[ Upstream commit 366228ed01f6882cc203e3d5b40010dfae0be1c3 ]
If some processes in nixge_probe() fail, free_netdev(dev)
needs to be called to aviod a memory leak.
Fixes: 87ab207981ec ("net: nixge: Separate ctrl and dma resources")
Fixes: abcd3d6fc640 ("net: nixge: Fix error path for obtaining mac address")
