IMO, it is a good idea to make _nvme_connect_subsys() return the device. The
similar function _nvmet_passthru_target_connect() does that, so it is another
small goodness to have consistency between the two.

I posted the fix patch for the nvme/047 problem reflecting your comments. I hope
that fix settled before further refactoring.

It is a fun to see the much of the boiler plates go away with the series :)
Thanks. I provided two minor comments on the 5th patch and 10th patch. Other
than that, this series looks good to me. Also I did another trial run, and
saw no regression. Good.
