    Prevent file system grow when partition grow fails (#686668)
    
    Prior to this enhancement, GParted ignored the status of the partition
    grow operation, and attempted to grow the file system.
    
    Now we check the status of the partition grow operation prior to
    growing the file system.
    
    Part of Bug #686668 - Growing logical partition overlaps end of
                          extended partition
