Fix undefined behavior in maybe_resize_hash_table
Problem discovered with GCC 16.1.1 -fsanitize=undefined.
* src/fns.c (maybe_resize_hash_table): Avoid undefined
behavior when h->key_and_value or h->hash are null pointers,
in which case we call memcpy (destination, NULL, 0)
which has undefined behavior in C89 through C23.
