No. Kiln drying whole cedar logs is not only unpractical it is very expensive. Cedar has superior shrinkage characteristics so Kiln drying does not provide a huge benefit. Kiln drying is very useful for interior applications such as furniture where the wood will stay in a constant climate. But because whole logs are exposed to the elements in a log home the logs moisture content will constantly change. The logs will air dry over time and by using proper settling details during construction there are no problems with using green logs.
