[ Upstream commit f8860ce836f2d502b07ef99559707fe55d90f5bc ]
If ieee80211_hw_restart() is called during authentication, the authentication process will continue, causing the driver to be called in a wrong state. This ultimately causes an oops in the iwlwifi driver (at least).
This fixes bugzilla 195299 partly.
