Hangbin Liu f3a63cce1b rtnetlink: Honour NLM_F_ECHO flag in rtnl_delete_link ...

This patch use the new helper unregister_netdevice_many_notify() for
rtnl_delete_link(), so that the kernel could reply unicast when userspace
 set NLM_F_ECHO flag to request the new created interface info.

At the same time, the parameters of rtnl_delete_link() need to be updated
since we need nlmsghdr and portid info.
