hostapd: fix WPA2 key replay security bug

Note, hostapd and wpa_supplicant use the same sources.  This commit is based
on Ross Burton's change to OpenEmbedded-core.  Below is Ross's commit message
from OpenEmbedded-Core.

    WPA2 is vulnerable to replay attacks which result in unauthenticated users
    having access to the network.

    * CVE-2017-13077: reinstallation of the pairwise key in the Four-way handshake

    * CVE-2017-13078: reinstallation of the group key in the Four-way handshake

    * CVE-2017-13079: reinstallation of the integrity group key in the Four-way
    handshake

    * CVE-2017-13080: reinstallation of the group key in the Group Key handshake

    * CVE-2017-13081: reinstallation of the integrity group key in the Group Key
    handshake

    * CVE-2017-13082: accepting a retransmitted Fast BSS Transition Reassociation
    Request and reinstalling the pairwise key while processing it

    * CVE-2017-13086: reinstallation of the Tunneled Direct-Link Setup (TDLS)
    PeerKey (TPK) key in the TDLS handshake

    * CVE-2017-13087: reinstallation of the group key (GTK) when processing a
    Wireless Network Management (WNM) Sleep Mode Response frame

    * CVE-2017-13088: reinstallation of the integrity group key (IGTK) when
    processing a Wireless Network Management (WNM) Sleep Mode Response frame

    Backport patches from upstream to resolve these CVEs.
