    Prevent 'index' may be used uninitialised warning in OperationDelete (#755214)
    
    I missed another case of 'index' may be used uninitialised warning in
    OperationDelete::apply_to_visual().  Indent a code block within an if
    clause so that the compiler can confirm that the 'index' local variable
    isn't used uninitialised.  Prevent this compiler warning:
        OperationDelete.cc: In member function 'virtual void 
GParted::OperationDelete::apply_to_visual(std::vector<GParted::Partition, std::allocator<GParted::Partition> 
> &)':
        OperationDelete.cc:34: warning: 'index' may be used uninitialized in this function
