Stanislaw Gruszka 731073b9c9 sky2: initialize napi before registering device
There is race condition when call netif_napi_add() after
register_netdevice(), as ->open() can be called without napi initialized
and trigger BUG_ON() on napi_enable(), like on below messages:

[    9.699863] sky2: driver version 1.30

To fix the problem patch changes the order of initialization.
