Subject: features/index: Delete granular entry indices of already healed
 directories during crawl

If granular name indices are already in existence for a volume, and
before they are healed, granular entry heal be disabled, a crawl on
indices/xattrop will clear the changelogs on these directories. When
their corresponding entry-changes indices are crawled subsequently,
if it is found that the directories don't need heal anymore, the
granular indices are not cleaned up.
This patch fixes that problem by ensuring that the zero-xattrop
also deletes the stale indices at the level of index translator.
