commit #1868cf308a3b3a336fcfe52c5aea4ac12d5e42ac breaks wireless on my system

[Maxim Levitsky <maximlevitsky@gmail.com>]

I use nl80211 wpa_suppicant driver.
With this commit (have just bisected) I can't connect to same AP twice,
and usually only a module reload, or somtimes restart of supplicant
help.
Actually usually I can't connect again after first successful connection
at all.


With wext supplicant works, but still sometimes hangs in same way.

    mac80211: don't try to do anything on unchanged genIE
    
    When the genIE hasn't changed there's no reason to kick
    the state machine since it won't be able to do anything
    new -- doing this decreases the useless work we do for
    reassociating because if we do kick the state machine
    it will try to find a usable BSS but there might not be
    one because wpa_supplicant will only change the BSSID
    a little later.
    
    In a sense this is a workaround for userspace behaviour,
    but on the other hand userspace cannot really keep track
    of what the kernel currently has for genIE since any
    process could have changed that while wpa_supplicant
    wasn't looking.
