    VirtualDisk: Fix logic error determining if we are creating storage
    
    If creating a storage volume, the logic would fall through and check if
    the path existed locally. This isn't valid for remote connections.
    
    Addtionally cleanup similar functions to be easier to read and hopefully
    avoid these problems in the future.
