Eric Dumazet 84adb42234 rtnetlink: make sure to refresh master_dev/m_ops in __rtnl_newlink() ...

commit c6f6f2444b upstream.

While looking at one unrelated syzbot bug, I found the replay logic
in __rtnl_newlink() to potentially trigger use-after-free.

It is better to clear master_dev and m_ops inside the loop,
in case we have to replay it.
