Set GTK rekey offload information after initial group key handshake

Browse Source 
The GTK rekey offload information was sent to the driver immediately
after the 4-way handshake which ended up being before the initial group
key exchange in the case of WPA (v1). This could result in even that
initial GTK handshake being offloaded and wpa_supplicant being left in
WPA_GROUP_HANDSHAKE state. Fix this by postponing the operation to
happen only after the full set of initial EAPOL-Key exchanges have been
completed (i.e., in the existing location for WPA2 and a after the group
key handshake for WPA).
