Removed the term subordinate since all datasets are promoted...

As discussed I added 10990 to the list of bugs being fixed here and
filed a new bug (bug 11641). This new bug covers only the check for
the zonepath when doing the promote of the zones' datasets.
I also reference bug 11641 in bug 10990.
