[PATCH v3 4/9] pack-bitmap: don't rely on bitmap_git->reuse_objects

[Christian Couder <christian.couder@gmail.com>]

From: Jeff King <peff@peff.net>

We will no longer compute bitmap_git->reuse_objects in a
following commit, so we cannot rely on it anymore to
terminate the loop early; we have to iterate to the end.
