performance/write-behind: reduce traversal of request list during wb_mark_winds.
- move all the decision making code to __wb_can_wind.
- don't continue traversing the request list, once we know any of the
following conditions are true:
* requests other than write are present in queue.
* writes are happening at non-contiguous offsets.
* there are no write requests, which are wound to server but not yet
received the reply.
* enough data is aggregated for writing.
