cocci & cache.h: fully apply "active_nr" part of index-compatibility

Apply the "active_nr" part of "index-compatibility.pending.cocci", which was left out in [1] due to an in-flight conflict. As of [2] the topic we conflicted with has been merged to "master", so we can fully apply this rule. 1. dc594180d9e (cocci & cache.h: apply variable section of "pending" index-compatibility, 2022-11-19) 2. 9ea1378d046 (Merge branch 'ab/various-leak-fixes', 2022-12-14) Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
