block/parallels: Avoid overflows
Change the types of variables in allocate_clusters() to int64_t so we do not have to worry about potential overflows. Add an assertion that our accesses to s->bat[] do not result in a buffer overflow and that the implicit conversion performed when invoking bat_entry_off() does not result in an integer overflow.
