why add this uint128 check? I don't think its necessary

[eswak]

on large values the CToken fails with MINT_EXCHANGE_CALCULATION_FAILED and there can be issues with wadMul, better to put a boundary (uint128.max is pretty large already)

[Joeysantoro]

right but its gas intensive to add. In practice token values don't get this large
