  SVN rev 205597 on 2010-03-24 14:50:04Z by kib
  
  MFC r204474:
  Fix the race between dotdot lookup and forced unmount, by using
  msdosfs-specific variant of vn_vget_ino(), msdosfs_deget_dotdot().
  
  As was done for UFS, relookup the dotdot denode after the call to
  msdosfs_deget_dotdot(), because vnode lock is dropped and directory
  might be moved.
  
  MFC r204675:
  When returning error from msdosfs_lookup(), make sure that *vpp is NULL.
