Fix bug if vehicle holds more soldiers than can fit in a squad (by Seven) (#103)

* Fix bug if vehicle holds more soldiers than can fit in a squad (by Seven)

We would fail Assert(fSuccess) as all passengers would not fit in one squad, and the code wouldn't allow creating a new squad where they could be placed.

* Add missing if conditional to previous fix
My bad
