block: Remove should_sort judgement when flush blk_plug
In commit 975927b942c932,it add blk_rq_pos to sort rq when flushing. Although this commit was used for the situation which blk_plug handled multi devices on the same time like md device. I think there must be some situations like this but only single device. So remove the should_sort judgement. Because the parameter should_sort is only for this purpose,it can delete should_sort from blk_plug.
