PG-338: Fix query call count (utilities). 

There was a missing increment/decrement to exec_nested_level in
pgss_ProcessUtility hook, due to this, some utility statements could
end up being processed more than once, as PostgreSQL may recurse into
this hook for sub-statements or when processing a query string
containing multiple semicolon-separated statements.
