afr: remove stale index entries
Problem: During pre-op phase, the index xlator 1. Creates the entry inside .glusterfs/indices/xattrop 2. Winds the xattrop fop to posix to mark dirty/pending changelogs. If the brick crashes after 1, the xattrop entry becomes stale and never gets removed by shd during subsequent crawls because there is nothing to heal (changelogs are zero). Though the stale entry does not get displayed in the output of 'heal info' command, it nevertheless stays there forever unless a new write transaction is performed on the file. Fix: During index self-heal if afr xattrs are found to be clean (indicated by ret value of 2 on a call to afr_shd_selfheal(), send a dummy post-op with all 0s for the xattr values, which makes the index xlator to unlink the stale entry.
