block: Don't check QUEUE_FLAG_SAME_COMP in __blk_complete_request
In __blk_complete_request, we check both QUEUE_FLAG_SAME_COMP and req->cpu to decide whether we should use req->cpu. Actually the user can also select the complete cpu by either setting BIO_CPU_AFFINE or by calling bio_set_completion_cpu. Current solution makes these 2 ways don't work any more. So we'd better just check req->cpu. Signed-off-by: Tao Ma <boyu.mt@taobao.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
