Use nbtdesc "level" field name consistently.

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 1c453cfd.
