Dmitry pointed out this potential overflow. They can't really happen
because of the `CheckTransaction` check on explicit amounts that
happens earlier in the verification chain. But it's a good idea to
add the check here as well so that a potential relaxing of other rules
cannot accidentally introduce an overflow risk.
