Don't clear the remoteDevice address in resetController()

The Bluez DBus peripheral role support cleared the remoteDevice so that
the QLowEnergyController::remoteAddress() will return empty after
disconnection.

However the resetController() is also called in client role
connectToDeviceHelper(), and by reseting the remoteDevice
address there, the controller won't find the remote device path and
connect will fail.

Instead clear the remoteDevice address in places specific to the
peripheral role.
