qa/tasks/cephadm_cases/test_cli: fix test_daemon_restart

We cannot schedule a daemon start if there is another daemon action
with a higher priority (including stop) scheduled.  However,
that state isn't cleared until *after* the osd goes down, the
systemctl command returns, and mgr/cephadm gets around to updating
the inventory scheduled_daemon_action state.

Semi-fix: (1) wait for the orch status to change, and then (2)
wait a few more seconds after that.
