mirror: do not flush every time the disks are synced
This puts a huge strain on the disks when there are many concurrent
migrations. With this patch we only flush twice: just before issuing
the event, and just before pivoting to the destination. If management
will complete the job close to the BLOCK_JOB_READY event, the cost of
the second flush should be small anyway.
