Fix Wiimotes not reconnecting on button press

5.0-56 broke reconnecting a Wiimote on button press; this is because
data reporting was now always stopped for real Wii remotes on
disconnect, making it impossible to know a button was pressed in the
first place (to reconnect the Wiimote).

This semi-reverts to the previous behaviour, where data reporting is
never stopped.

(Also, control channels now go through WiimoteEmu, just like before,
to make sure some things are reset on disconnection.)

Hopefully fixes issue 9711.
