netlink_delinearize: unused code in reverse cross-day meta hour range

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.

Add test for cross-day scenario in EADT timezone.
