Description:
If doing a parallel node restart,
the starting node could (sometimes) incorrectly sync subscriptions among themselves.

Which is sort of pointless, as they don't have any subscriptions.
This can lead to replication stop.

How to repeat:

        Make sure that SUMA_START_ME only goes to alive nodes
        (i.e not to starting nodes)

Documented bugfix in the NDB 6.2.16 and 6.3.17 changelogs as follows:

        During a parallel node restart, the starting nodes could (sometimes)
        incorrectly synchronize subscriptions among themselves. Instead, such
        this synchronization now takes places only among nodes that have
        actually (completely) started.
