audit: init ab->skb_list earlier in audit_buffer_alloc()
syzbot found a bug in audit_buffer_alloc() if nlmsg_new() returns NULL.
We need to initialize ab->skb_list before calling audit_buffer_free()
which will use both the skb_list spinlock and list pointers.
Fixes: eb59d494eebd ("audit: add record for multiple task security contexts")
