tools/target_dec_fuzzer: move maximum variables into function

This fixes an issue when multiple cases are fuzzed in a single run and
the limits are adjusted by more than the iteration limit. In that case
the adjusted limit leaked back into the global limit causing the
fuzzer to become ineffective after several iterations, MSS2 was
affected by this for example.
