This is my attempt to address the issues I mentioned last week.  It is
still under development and doesn't work yet.  I thought it did.

I'm now trying to get my brain around what that code is doing with
Kconfig symbols and net_prio_subsys_id.  I'm suspecting it's all to
make cgroup-subsys-within-a-module appear to work.

afaict net_prio_subsys_id is an enum if CONFIG_NETPRIO_CGROUP=y and is
an `extern int' when CONFIG_NETPRIO_CGROUP=m.  It's unclear to me why
the extern int version or net_prio_subsys_id exists at all, really.
