mgr/cephadm: The command of 'ceph orch daemon restart mgr.xxx' may case mgr daemon loop to restart
Scene:
The mgr daemon is active. After execing restart command, it may be save "scheduled_daemon_actions": {"mgr.xxx": "restart"}}" to config-key.
So the mgr daemon will restart before call rm_scheduled_daemon_action which case mgr daemon will load restart forever.

Fix mgr infinite restart issue refering to the same solution as 'ceph orch daemon redeploy'.
