While a lot of people share this misconception, growing biofuels and then burning them does not result in a net increase in atmospheric CO2, since the carbon in these fuels is taken from the atmosphere. It's only when we burn hydrocarbons from non-renewable sources that it's an issue. For example, burning wood and oil adds CO2 to the atmosphere faster than photosynthesis removes it, whereas burning a biofuel can at most reach the same level as that being taken from the atmosphere.
However, you do have a good point if you consider the fact that the land used to grow crops would usually have removed more CO2 than it does once used for biofuel.
