wifi: rtw89: chan: tweak bitmap recalc ahead before MLO
Originally, we just declared two sub-entity, and according to rolling
down mechanism, we ensured that index 0 contained sub-entity as long
as there are sub-entity. So, we could use for-loop after deciding the
last index.
But, we are preparing to expand num of sub-entity for MLO. Then, there
won't be just two sub-entity. And, there might be holes between two bits
in the bitmap. So, we cannot simply do for-loop as before. Instead, we
need to follow the set bits.
