block: mark flush request as IDLE when it is really finished
For avoiding use-after-free on flush request, we call its .end_io() from
both timeout code path and __blk_mq_end_request().
When flush request's ref doesn't drop to zero, it is still used, we
can't mark it as IDLE, so fix it by marking IDLE when its refcount drops
to zero really.
