[PATCH v3 04/15] mesh: use setup completion callback to complete mesh join

[peter.oh at bowerswilkins.com]

From: Peter Oh <peter.oh at bowerswilkins.com>

mesh join function is the last function to be called during
mesh join process, but it's been called a bit earlier than
it's supposed to be, so that some mesh parameter values
such as VHT capabilities not applied correct when mesh join
is in process. Moreover current design of mesh join that is called
directly after mesh initialization is not suitable for DFS channels
to use, since mesh join process should be paused until DFS CAC is
done and resumed once it's done.
Using setup completion callback is how AP mode is using for DFS channels
and mesh can use the same way.
The callback will be called by hostapd_setup_interface_complete_sync.
