Invalid joystick identification via LED after connection loss

[Sergii Bezpalyi]

To reproduce this issue you need two joystics.
Steps to reproduce:
1. Connect both joysticks to system using bluetooth. Each joystick correctly identified by LED on it's back.
2. Take first joystick and walk away from computer, you should wait until led are off.
3. Return to computer and hit the PS button.
4. Joystick succesfully reconnected as js0 but LED on the joystick back shows him as number two.
It's only display issue, both joysticks are working fine, but I can't find which one is the first.
