[v3] xfs: test statfs on project quota directory

Commit Message

There's a bug on xfs cause statfs get negative f_ffree value from
a project quota directory. It's fixed by "de7243057 fs/xfs: fix
f_ffree value for statfs when project quota is set". So add statfs
testing on project quota block and inode count limit.

Hi,

Thanks Carlos helped to review the V2 patch, V3 did below changes:
1) Remove project quota config files, turn to use 'project -p <path>'
2) Modify some comments

Thanks,
Zorro
