RDMA/ipoib: Set rtnl_link_ops for ipoib interfaces
Report the "ipoib pkey", "mode" and "umcast" netlink attributes for every
IPoiB interface type, not just children created with 'ip link add'.
After setting the rtnl_link_ops for the parent interface, implement the
dellink() callback to block users from trying to remove it.
Fixes: 862096a8bbf8 ("IB/ipoib: Add more rtnl_link_ops callbacks")
