congestion_wait() in this context is just a sleep - block devices do not
in general support congestion signalling any more.
The goal here is to wait for any recently written data to get to
storage. blkdev_issue_flush() is thought to be too expensive, so
replace congestion_wait() with an explicit timeout.
