[ Upstream commitb98e1a04e2] Once a socket has been unhashed, we want to prevent it from being re-used in a sk_key entry as part of a routing operation. This change marks the sk as SOCK_DEAD on unhash, which prevents addition into the net's key list. We need to do this during the key add path, rather than key lookup, as we release the net keys_lock between those operations.
