Fix up the compare chain in nstime_delta().

The first case handles the two time stamps having the same seconds
value, so, in the subsequent cases, they're guaranteed not to have the
same seconds value; check for b->secs < a->secs, not for b->secs <= a->secs
(the two tests will always get the same value, as b->secs != a->secs),
to make it clearer what's being done.
