Hi Jens

After commit c616cbee ( blk-mq: punt failed direct issue to dispatch
list ), we always insert request to hctx dispatch list whenever get a
BLK_STS_RESOURCE or BLK_STS_DEV_RESOURCE, this is overkill and will
harm the merging. We just need to do that for the requests that has
been through .queue_rq.

This patch set fixes the issue above and refactors the code of issue
request directly to unify the interface and make the code clearer and
more readable.

Please consider this patchset for 4.21.

Applied, thanks Jianchao.
