The statfs reports incorrect free/available space
for quota less then CEPH_BLOCK size (4M).

The approach chosen is to go with binary use/free
of full block instead of chosing the smaller block
size.

For quota size less than CEPH_BLOCK size, report
the total=used=CEPH_BLOCK,free=0 when quota is
full and total=free=CEPH_BLOCK, used=0 otherwise.
