[PATCH net, 1/2] net: core: Fix missing init of llist_node in setup_net()

[Haiyang Zhang <haiyangz@linux.microsoft.com>]

From: Haiyang Zhang <haiyangz@microsoft.com>

Add init_llist_node for lock-less list nodes in struct net in
setup_net(), so we can test if a node is on a list or not.

Cc: stable@vger.kernel.org
Fixes: d6b3358a2813 ("llist: add interface to check if a node is on a list.")
