[PATCH net v2 1/2] wireguard: device: don't call free_netdev() in priv_destructor()

[Yang Yingliang]

After commit cf124db566e6 ("net: Fix inconsistent teardown and..."),
priv_destruct() doesn't call free_netdev() in driver, we use
dev->needs_free_netdev to indicate whether free_netdev() should be
called on release path.
This patch remove free_netdev() from priv_destructor() and set
dev->needs_free_netdev to true.
