Omit SMB audit results from audit.query output by default

This is an optimization to improve memory consumption by default
queries used by the webui. Initially we included SMB audit results
by default with the expectation that user would specify the exact
audited service they wanted to query. Since SMB audit logs can
span upwards to hundreds of thousands of entries in some extreme
cases we need to ensure that UI / API consumers use optimized
SQL queryfilters with appropriate pagination.
