Revert "init: Enable StopWhenUnneeded"

This reverts commit 03d9321bc80887d4578744c26c05d61e2d9d4278.

Reverted because when corosync service is not enabled and corosync
is executed by "systemctl start corosync" it is then immediately
shutdown because of "Unit not needed anymore. Stopping.".

This is really not expected behavior.
