Bugfix: harden hash-next, since it is exposed.
The C code doesn't call hash_next once it returns nil,
so it doesn't matter that doing so will dereference
a null pointer. But hash_next is now exposed as
the Lisp function hash-next.
* hash.c (hash_next): If the hash table in the iterator
is nil, then return nil, avoiding the dereference of
a null pointer.
