f8f32deda31d ("meta: Introduce new conditions 'time', 'day' and 'hour'")
reverses a cross-day range expressed as "22:00"-"02:00" UTC time into
!= "02:00"-"22:00" so meta hour ranges works.
Listing is however confusing, hence, 44d144cd593e ("netlink_delinearize:
reverse cross-day meta hour range") introduces code to reverse a cross-day.
However, it also adds code to reverse a range in == to-from form
(assuming OP_IMPLICIT) which is never exercised from the listing path
because the range expression is not currently used, instead two
instructions (cmp gte and cmp lte) are used to represent the range.
Remove this branch otherwise a reversed notation will be used to display
meta hour ranges once the range instruction is to represent this.
While at it, unreliable test dump:
tests/shell/testcases/listing/dumps/meta_time.nft
and move the cross-day check to the test script.
Fixes: 44d144cd593e ("netlink_delinearize: reverse cross-day meta hour range")
