heal: Fix incorrect heal info output

        Backport of: http://review.gluster.org/14199

Problem:
In heterogenous clusters, heal info gives incorrect
outout as "Failed to process entries completely.
Number of entries so far: 0".

This happens when the getxattr on virtual xattr
for <brickpath>/.glusterfs/indices/dirty fails
on older bricks as they do not recognize the xattr.

Fix:
Ignore that error so that heal info doesn't
incorrectly report failure.
