Add runtime checks for bogus multixact offsets

It's not far-fetched that we'd try to read a multixid with an invalid
offset in case of bugs or corruption. Or if you call
pg_get_multixact_members() after a crash that left behind invalid but
unused multixids. Better to get a somewhat descriptive error message
if that happens.
