After key negotiation completed using wpa_supplicant, wpa_supplicant
can't reassoc with the AP if we reboot the AP. It always fails at the
4-way handshake.
The problem is the key info is not cleared correctly. Thus when
wpa_supplicant send the EAPOL-KEY packet, the d80211 stack finds the old
key and uses it to encrypt the packet.
The patch removes the sta_info when we disassociate with AP.

Wouldn't it be better to move this into the 'else' branch of previous
'if' statement (i.e. just before sta_info_put call in the
ieee80211_associated function)?
Rework the patch according to Jiri's comments.
