Summary

We always start out using the 10-byte version of READ DEFECT DATA, and
then switch to 12-byte when necessary due to errors or data length
requirements. We always need to get the length again when we do this,
and we're always going to be using 12-byte commands from that point
forward. Simplify the logic a bit based on this observation.
