cluster/ec: Get size of file in EC [f]xattrop
Problem: For allowing parallel writes we shouldn't depend on ia_size to be same for all the bricks in each write_cbk(). But we need to make sure backend size is correct on all the bricks and no crashes/manual modifications happened. Fix: At the time of get_size_version() we do 1 check to make sure size of the file is same across the bricks. From then on the FOPs will give the status of the fop, so we rely on this information to keep which bricks are good/bad.
