net, wireless: overwrite default_ethtool_ops
Since:
commit 2c60db037034d27f8c636403355d52872da92f81

net: provide a default dev->ethtool_ops
wireless core does not correctly assign ethtool_ops.
After alloc_netdev*() call, some cfg80211 drivers provide they own
ethtool_ops, but some do not. For them, wireless core provide generic
cfg80211_ethtool_ops, which is assigned in NETDEV_REGISTER notify call:
if (!dev->ethtool_ops)
dev->ethtool_ops = &cfg80211_ethtool_ops;
But after Eric's commit, dev->ethtool_ops is no longer NULL (on cfg80211
drivers without custom ethtool_ops), but points to &default_ethtool_ops.
In order to fix the problem, provide function which will overwrite
default_ethtool_ops and use it by wireless core.
