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.
