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/20200206213825.11444-1-farman@linux.ibm.com/

I did leave a couple things FIXMEs from v1 comments in here.
Thought it'd be best to just get this out with the kernel code, to
make sure things aren't too far in the weeds.

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