geneve: Suppress list corruption splat in geneve_destroy_tunnels().
[ Upstream commit 62fab6eef61f245dc8797e3a6a5b890ef40e8628 ]
As explained in the previous patch, iterating for_each_netdev() and
gn->geneve_list during ->exit_batch_rtnl() could trigger ->dellink()
twice for the same device.
If CONFIG_DEBUG_LIST is enabled, we will see a list_del() corruption
splat in the 2nd call of geneve_dellink().
Let's remove for_each_netdev() in geneve_destroy_tunnels() and delegate
that part to default_device_exit_batch().
Fixes: 9593172d93b9 ("geneve: Fix use-after-free in geneve_find_dev().")
