name-hash: use expand_to_path()
A sparse-index loads the name-hash data for its entries, including the
sparse-directory entries. If a caller asks for a path that is contained
within a sparse-directory entry, we need to expand to a full index and
recalculate the name hash table before returning the result. Insert
calls to expand_to_path() to protect against this case.
