bridge: Assign rtnl_link_ops to bridge devices created via ioctl (v2)

[ Upstream commit 149ddd83a92b02c658d6c61f3276eb6500d585e8 ]

This ensures that bridges created with brctl(8) or ioctl(2) directly
also carry IFLA_LINKINFO when dumped over netlink. This also allows
to create a bridge with ioctl(2) and delete it with RTM_DELLINK.
