net: deinit automatic LIST_HEAD
commit 9b5e383c11b08784 (net: Introduce unregister_netdevice_many()) left an active LIST_HEAD() in rollback_registered(), with possible memory corruption. Even if device is freed without touching its unreg_list (and therefore touching the previous memory location holding LISTE_HEAD(single), better close the bug for good, since its really subtle. (Same fix for default_device_exit_batch() for completeness) Reported-by: Michal Hocko <mhocko@suse.cz> Tested-by: Michal Hocko <mhocko@suse.cz> Reported-by: Eric W.
