Beau Belgrave 17b439db21 tracing/user_events: Ensure bit is cleared on unregister 
If an event is enabled and a user process unregisters user_events, the
bit is left set. Fix this by always clearing the bit in the user process
if unregister is successful.

Update abi self-test to ensure this occurs properly.
