distribute: bring in feature to fix the layout of root inode

* If the errno is ESTALE for root, fuse doesn't send fresh lookup on
  the path (it does for all other inodes). Earlier layout mismatch for
  root never used to happen inside codebase, and if noticed, it was
  serious issue.

  Now with DVM, after a add-brick or a remove-brick, layout can be
  changed even for 'root' inode. Needed to fix this issue inside
  distribute itself, instead of fuse sending 'fresh' lookup on root.
