Description:
Currently MySQL cannot be started with --replicate-same-server-id and --log-slave-updates. MySQL refuses to restart with the following error

"using --replicate-same-server-id in conjunction with --log-slave-updates is impossible, it would lead to infinite loops in this server."

But with gtid_mode=ON, I don't think infinite loops are possible. GTID feature is built to handle circular topology.

How to repeat:
see description

Suggested fix:
relax the restriction by checking for gtid_mode=ON
