Description of problem:
========================
In the existing self-heal algorithm, the self-heal happens from the node which has wise change-logs. 

Lets say there are 3 bricks in the cluster (1 x 3 replicate volume). writes are happening on a file and brick1 crashes. writes still continue to happen from mount point. Brick1 is brought online. Before self-heal could complete brick2 crashed. At this point of time brick2 had [ 265 0 0 ] change-logs on a file. writes still continue to happen . brick3 crashes. (brick3 is the longest lived brick) . When both brick2 and brick3 are brought online, self-heal happens from brick2 to brick3 and brick1 even though brick3 has the latest data. This is because the change-logs of the file on brick2 indicates it's wise.

===================

Steps to Reproduce:
======================
1. On a 1 x 3 replicate volume, opened fd on 10 files. started writing data on all the files. writes on the file were in progress all the time. {periodic writes }

2. Brought down brick1 (xfs_progs -> godown)

3. After some time brought back brick1.

4. Before the self-heal could complete, brick2 crashed.(xfs_progs -> godown)

At this point of time the extended attributes of one of the file on brick2 was, [ 265 0 0 ]

5. After some time brick3 crashed.(xfs_progs -> godown)

At this point of time the extended attributes of one of the file on brick2 was, [ 266 140 1 ]

6. brought back brick2 and brick3 at same time.

Actual results:
==================
Self-heal happened from brick2 to brick1 and brick3 on this files.
