rdma: rename 'x-rdma' => 'rdma'

As far as we can tell, all known bugs have been fixed:

1. Parallel migrations are working
2. IPv6 migration is working
3. virt-test is working

I'm not comfortable sending the revised libvirt patch
until this is accepted or review suggestions are addressed,
(including pin-all support. It does not make sense to
remove experimental for one thing and not the other. That's
too many trips through the libvirt community).
