:wave: Hey,

This PR fixes #8114

We were accidentally using the max opcode in the min helper when using the Zbb extension. This wasn't caught by testing since we never enabled the smin tests with the Zbb extension enabled.

Furthermore this should have been caught by fuzzing, but we also don't regularly fuzz RISC-V. (And I haven't ran it manually in quite a while)
