f2fs: fix miscounted block limit in f2fs_statfs_project() 

commit acdf217217 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.
