Subject: [PATCH 18/30] mkfs.ocfs2: create root and orphan directories as indexed

If the indexed dirs feature is enabled but the inline directories feature is
for some reason disabled, we'll create sub-optimal (non-indexed) root and
orphan directories. It's easy however at the end of mkfs.ocfs2 to simply
index these.
