osd: requeue blocked op before flush it was blocked on

If we have request A (say, cache-flush) that blocks things, and then
request B that gets blocked on it, and we have an interval change, then we
need to requeue B first, then A, so that the resulting queue will keep
A before B and preserve the order.

This was observed on this firefly run:
