What problem does this PR solve?

Issue Number: close #33538

Problem Summary:
globalkilltest TestMultipleTiDB failed.

What is changed and how it works?

When #17649 introduces global kill, in (*Domain).Init, we first call do.acquireServerID to get server ID and then call infosync.GlobalInfoSyncerInit to store server ID to etcd. #28945 switches the order between do.acquireServerID and infosync.GlobalInfoSyncerInit and thus we store server ID zero to etcd, which causes the failure of TestMultipleTiDB. The pr switches the order back to fix the test case.

P.S. It would be better to add "tests/globalkilltest" to CI later, to avoid similar issue again. But it seems to be not stable now and need some improvement.
