refactor: Avoid sign-compare compiler warning in util/asmap

This reverts commit eac6a3080d38cfd4eb7204ecd327df213958e51a ("refactor:
Rework asmap Interpret to avoid ptrdiff_t"), because it is UB to form a
past-the-end iterator, even if it is never dereferenced.

Then fix the compiler warning in a different way:
Instead of comparing an uint32_t against a signed ptrdiff_t, just
promote both to a type that can represent both types.

Even though in this case the ptrdiff_t should never hold a negative
value, the overhead from promotion should be negligible.
