[DR] add and remove protection to a server leads to DRBD on DR being stuck

testing in a loop by adding and removing protection from a server:

```
[root@an-a01n01 ~]# drbdadm status
an-test-deploy1 role:Primary
disk:UpToDate open:yes
an-a01n02 role:Secondary
peer-disk:UpToDate
ci connection:Connecting

[root@ci ~]# drbdadm status an-test-deploy1
an-test-deploy1 role:Secondary
disk:Diskless open:no
an-a01n01 connection:StandAlone
an-a01n02 connection:StandAlone
```

and waiting for a while doesn´t recover from that status.
