As with the preceding change for "reflog delete", change the "cb_data" we pass to callbacks to be &cb.cmd itself, instead of passing &cb and having the callback lookup cb->cmd. This makes it clear that the "cb" itself is the same memzero'd structure on each iteration of the for-loops that use &cb, except for the "cmd" member. The "struct expire_reflog_policy_cb" we pass to reflog_expire() will have the members that aren't "cmd" modified by the callbacks, but before we invoke them everything except "cmd" is zero'd out. This included the "tip_commit", "mark_list" and "tips". It might have looked as though we were re-using those between iterations, but the first thing we did in reflog_expiry_prepare() was to either NULL them, or clobber them with another value.
