Ticket 50790 - Add result text when filter is invalid
Bug Description: As a result of the change in 50727
we need to communicate to users/admins when queries they issue
may be incomplete due to rfc compliance of filter processing.
Fix Description: When we use idl_alloc(0) on attributes, we set
a result text (if none already set) warning that the result set
may be incomplete.
