bulk-checkin: fix leaking state TODO

When flushing a bulk-checking to disk we also reset the `struct
bulk_checkin_packfile` state. But while we free some of its members,
others aren't being free'd, leading to memory leaks:

  - The temporary packfile name is not getting freed.

  - The `struct hashfile` only gets freed in case we end up calling
    `finalize_hashfile()`. There are code paths though where that is not
    the case, namely when nothing has been written. For this, we need to
    make `free_hashfile()` public.

Fix those leaks.
