[PATCH v4 05/12] pack-check: stop depending on `the_repository`

From

In-Reply-To

There are multiple sites in "pack-check.c" where we use the global `the_repository` variable, either explicitly or implicitly by using `the_hash_algo`. In all of those cases we already have a repository available in the calling context though.

Refactor the code to instead use the caller-provided repository and remove the `USE_THE_REPOSITORY_VARIABLE` define.
