staging: slicoss: use free_netdev(netdev) instead of kfree() 

Author: Vasiliy Kulikov <segooon@gmail.com>

Freeing netdev without free_netdev() leads to net, tx leaks.
I might lead to dereferencing freed pointer.

The semantic match that finds this problem is as follows:

struct net_device* dev;

-kfree(dev)
+free_netdev(dev)
