    Allow locking simplex controller

    After installing a controller, if it is unlocked before reconfiguring
    the required interfaces, the installation cannot be completed.
    This commit to allow locking the controller while it is in simplex
    state. This commit also reject unlocking controller in a duplex system
    if the management and cluster-host interfaces are on the loopback
    interface.

    After making the active controller on a duplex system return to a
    simplex state by locking and removing a standby controller, the address
    of the cluster-host interface was not unallocated properly. This commit
    corrected this problem.
