Fix spinner not shows up

Issue: We reset the deviceList when onCreate in discoveryService
But when user cancel the action, and re-associate, onCreate in
activty is happend before onCreate discoveryService.

How to fix: Reset the deviceList when onDestroy in discoveryService
to make sure to have a fresh start when user re-associate.
