Bug Description

If we create two share-networks with same data and same 'active_directory' security service and use it for CIFS share creation: then only first creation will be successful, second will fail with next error:

    Fix creation of cifs entry in cmode driver

    Cmode driver tries to create NetBIOS name in cifs server and fails, because
    this name should be unique, but driver did not use unique value for it.
    Also removed silent passing when cifs entry was not created.
