Use nbtdesc "level" field name consistently.

petergeoghegan · petergeoghegan · commit 2584639653ee · 2023-04-19T12:15:15.000-07:00
The "lev" name that appeared in NEWROOT nbtree record desc output was inconsistent with the symbol name from the underlying C struct. It was also inconsistent with nbtdesc output for other nearby record types with similar level fields. Standardize on "level" to make everything consistent. Follow-up to commit 1c453cf.
