8276540: Howl Full CardSet container iteration marks too many cards

[tschatzl]

Hi all,

can I have reviews for this change that fixes how many cards are being iterated over during Howl Full CardSet container iteration? There is no need to iterate over max_cards_in_region() cards, it is sufficient to iterate just over the area that this Howl partition represents, i.e. num_cards_in_howl_bitmap().

I will change the way to iterate over this card set container within the howl container in JDK-8276548 to keep this change small.

Testing: tier1-5 (with JDK-8276548).
