pbio/drv/bluetooth: Fix duplicate reset handler reset.

Write after free is already protected wth the finalizer. We shouldn't be unsetting the notification handler from a static config struct. This caused notifications to be lost when running the program again.

This only affected the Xbox Controller because the LWP3Device/Remote sets it every time.
