Antonio reported that RSN IBSS failed to work.
We traced it down to a GTK failure, and he then
bisected it to commit bdffdc5ddb0c838af4c90d11:
"AP: Reorder WPA/Beacon initialization".

The reason this commit broke it is that the state
machine's GInit variable is never set to false as
wpa_init_keys() never gets called, and thus new
keys are generated every time the state machine
executes.

Fix this by calling wpa_init_keys() when the new
group has been initialised.
