- disable wifi (user setting) and hard rfkill it
- then un-hard rfkill it, whereafter rfkill states (soft/hard) will go

    * from 0/0 to 1/0

The problem with this is that enabling wifi takes quite some time and
in between ConnMan will soft block wifi to disable it (according to
previous user setting). Thus it will request to disable wifi but since
enabling is still going on, this request won't do anything. Meanwhile

properly by ConnMan, the wifi_enable() callback will be called and the
