Reduce the nodelock count for both cache and regular rbtdb

Browse Source 
Increasing the nodelock count had major impact on the memory footprint
in scenarios where multiple rbtdb structure would be created like
hosting many zones in a single server.

This reverts commit 0344684385 and sets
the nodelock count to previously used values.
