[PATCH v2 6/8] fetch-pack: move common check and marking together

[Jonathan Tan <jonathantanmy@google.com>]

When receiving 'ACK <object-id> continue' for a common commit, check if
the commit was already known to be common and mark it as such if not up
front. This should make future refactoring of how the information about
common commits is stored more straightforward.

No visible change intended.
