commit acdf2172172a511f97fa21ed0ee7609a6d3b3a07 upstream.
statfs calculates Total/Used/Avail disk space in block unit, so we should translate soft/hard prjquota limit to block unit as well.
Below testing result shows the block/inode numbers of Total/Used/Avail from df command are all correct afer applying this patch.
