mcpu: Start locking at correct level

Commit 8716b1d added a new lock level, LEVEL_NODE_ALLOC. It is ahead of

We have many cases in the code where we write TOr(TNone, a), so let's
introduce a combinator that simplifies this case.

Beside replacing the above with TMaybe(a), I did a few other parameter
