pack-bitmap.c: more aggressively free in free_bitmap_index()

The function free_bitmap_index() is somewhat lax in what it frees. There are two notable examples: - While it does call kh_destroy_oid_map on the "bitmaps" map, which maps commit OIDs to their corresponding bitmaps, the bitmaps themselves are not freed. Note here that we recycle already-freed ewah_bitmaps into a pool, but these are handled correctly by ewah_pool_free(). - We never bother to free the extended index's "positions" map, which we always allocate in load_bitmap(). Fix both of these. Signed-off-by: Taylor Blau <me@ttaylorr.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
