Log:
i124091 - Drop check for nonlinearity

It appears the check for non-linearity is causing failures for cases that 
can be solved by CoinMP and other solvers. We don't really have a 
non-linear solver but it doesn't make sense to check for linearity here.

Thanks to Ted Ralphs for pointing the exact code causing the failure.
