While we should look at changing blk-mq to give better workqueue performance,
a bigger gain is likely to be made by adding a new host API to enable the
next already-prepared request to be issued directly from within ->done()
callback of the current request.

I assume that is taken care of by adding the new host cap
(MMC_CAP_DIRECT_COMPLETE).

So, then it's just a matter of adopting all host drivers, and when we
are done with that, we can remove that cap. :-)

Ehh, I realize that this not what you really propose, but rather this
is a next step of improvement. Anyway.
