 Change the dump iteration to be independent from
increasing radio indices on radio list.

You can't do that, data structures can be deleted while the dump is
ongoing.

That's what I try to address with this patch. In the past there were
corner cases, which might have failed while deletion.

Nonetheless, the radio count is in the current version strictly
monotonic, maybe the description is misleading. :-)
So in the inner loop there is no deletion possible because of the
spinlock, and multiple calls of nl=5Fdump check the generation count and
cancel if it have changed.
