nft monitor calls interval_map_decompose() even though it should not
in this case.  After fix this shows:

add rule bridge filter INPUT ether saddr . ip saddr { 08:00:27:40:f7:09 . 192.168.56.10, 08:00:27:40:f7:09 . 192.168.56.10 } counter

... instead, which looks correct (even though
the concat range is technically not required in this case).
