An addition to fix for MDEV-5205, fixes server crash on shutdown.

Thread groups are destroyed asynchronously, that is kill server thread sends shutdown request to all thread groups without waiting for compeltion.

It means all_groups array must not be freed until all thread groups are down. This patch suggests that all_groups is freed when last thread group is destroyed.

Looks reasonable. ok to push Regards, Sergei
