cluster/dht: Correct min_free_disk behaviour
Problem: Files were being created in subvol which had less than min_free_disk available even in the cases where other subvols with more space were available. Solution: Changed the logic to look for subvol which has more space available. In cases where all the subvols have lesser than Min_free_disk available , the one with max space and atleast one inode is available. Known Issue: Cannot ensure that first file that is created right after min-free-value is crossed on a brick will get created in other brick because disk usage stat takes some time to update in glusterprocess. Will fix that as part of another bug.
