Fix bug in auto-exporting subordinate mounts.

When mountd gets a request to export a mountpoint which is not
explicitly exported, but is below an export point that is flagged as
"crossmnt", it passes the wrong path name to the kernel for the
  "filehandle -> directory"
mapping.
This can badly confuse the NFS client, and is certainly wrong.

So use the correct path names.
