Fix a few bugs in nfsrv_rename() error recovery code.

- Prevent a double vrele() by setting the vnode pointer to NULL.
- Check if vnode pointers have been set to NULL before trying to
  vrele().
- don't double free the component path name buffer.
- Add a workaround for multiple vnode pointers all pointing to the
  same vnode and the code doing vrele() on all of them, leading to
  botched refcounts. This is a horrible hack, but a real fix is being
  worked on.
