Use != instead of < to future-proof sv_team

Assume that this branch should apply to all team modes except `SV_TEAM_FORCED_SOLO` also when new team modes would get added after `SV_TEAM_FORCED_SOLO` in the future, as the values will never be changed and there is no relation between the order of the numeric values and the behavior.
