Thanks, applied (also with the HT40 flag handled bit differently).
Please note that this operation is somewhat problematic since there is
an additional coex scan when the GO is started for the provisioning
step. This can take quite some time and the peer should be notified of
that. I added another commit that increases the GO config timeout value,
but this is not perfect since the current coex scan takes actually
longer than the maximum config timeout value with some drivers. In
addition, the channel may change (swap pri/sec) based on the coex scab.
wpa_supplicant as a P2P client should be able to handle these changes,
but it should be kept in mind that this is something that has not really
been thoroughly tested with deployed P2P implementations.
