iwlwifi3945/4965: fix rate control algo reference leak

Browse source 
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
