IOS-XR: Fix iosxr_lag_interfaces intermittent failures (#62998)

* Fix iosxr_lag_interfaces intermittent failures

*  If the dictionary is read out of order from member
   the current logic in `diff_list_of_dicts` returns
   unwanted diff. Hence use `dict_diff` utils
   function instead of sets.

Remove zip() to make existing tests happy
