netprio_cgroup: allow nesting and inherit config on cgroup creation
Inherit netprio configuration from ->css_online(), allow nesting and
remove .broken_hierarchy marking. This makes netprio_cgroup's
behavior match netcls_cgroup's.
Note that this patch changes userland-visible behavior. Nesting is
allowed and the first level cgroups below the root cgroup behave
differently - they inherit priorities from the root cgroup on creation
instead of starting with 0. This is unfortunate but not doing so is
much crazier.
