Revert "hostfs: fix the host directory parse when mounting."

This reverts commit be80de30 which is
commit ef9ca17c upstream.

It is reported to cause build issues and odds are the root problem isn't
really an issue on the 6.6.y branch anyway.  If it is, someone can
provide a working set of backported patches.
