iwlwifi3945/4965: fix rate control algo reference leak
Fix rate control algo reference leak in case if network device has been
failed to register. In this case special flag priv->mac80211_registered is
not set and the rate algo reference is not freeing on module unload. That
leads to OOPs in further ieee80211 rate register/unregister procedure (by
any callee).
It should fix the bug #9470
