DPP2: Disconnect before starting reconfiguration

The offchannel operations (scan, Public Action frame TX/RX) have
significantly more latency when performed while connected, so disconnect
when requested to initiate DPP reconfiguration to avoid this. The old
network profile (i.e., likely the current connection) is going to be
replaced in practice and as such, there is no need to try continue that
association any further.
