Here is a new pass at the channel-path handling code for vfio-ccw,
to take advantage of the corresponding kernel patches posted here:

https://lore.kernel.org/kvm/20200417023001.65006-1-farman@linux.ibm.com/

Per the discussion in v2, I dropped the EIO-to-CC3 patch from the
head of the series.

I also added a patch to refactor css_queue_crw(), so we can get a
CRW queued with a fully-qualified CRW we get out of this region
instead of extracting/recreating it.

Besides that, changes should be in the git notes for each patch.

v2: https://lore.kernel.org/qemu-devel/20200206214509.16434-1-farman@linux.ibm.com/
v1: https://lore.kernel.org/qemu-devel/20191115033437.37926-1-farman@linux.ibm.com/
