fs: fat: set start cluster for root directory
When iterating over a child directory we set itr->start_clust.
Do the same when over the root directory.
When looking for deleted directory entries or existing short names we will
have to iterate over directories a second and third time. With this patch
we do not need any special logic for the root directory.
