[PATCH 3/3] gc: perform incremental repack when implictly enabled

[Glen Choo <chooglen@google.com>]

builtin/gc.c has two ways of checking of multi-pack-index is enabled:
- git_config_get_bool() in incremental_repack_auto_condition()
- the_repository->settings.core_multi_pack_index in
  maintenance_task_incremental_repack()

the_repository->settings.core_multi_pack_index should be preferred
because it has default values from prepare_repo_settings().

Standardize on the_repository->settings.core_multi_pack_index to check
if multi-pack-index is enabled.
