prov/verbs: Enable implicit dmabuf mr reg for more HMEM ifaces

Now all the non-system HMEM ifaces have get_dmabuf_fd method defined,
it's safe to always try the dmabuf based memory registration first.
If it fails for any reason (e.g. CUDA is not configured with dmabuf
support), the failover path will try the peer memory approach when
available.
