pgsql: Remove unused parameter in lookup_var_attr_stats

Remove unused parameter in lookup_var_attr_stats

The parameter 'rel' in lookup_var_attr_stats was once used to draw an
ERROR when ANALYZE failed to acquire sufficient data to build extended
statistics. bf2a691e0 changed the logic to raise a WARNING in the
caller instead. As a result, this parameter is no longer needed and
can be removed. Since this is a static function, we can always easily
reintroduce the parameter if it's ever needed in the future.
