kernfs: Change kernfs_notify_list to llist.
At present kernfs_notify_list is implemented as a singly linked list of kernfs_node(s), where last element points to itself and value of ->attr.next tells if node is present on the list or not. Both addition and deletion to list happen under kernfs_notify_lock. Change kernfs_notify_list to llist so that addition to list can heppen locklessly.
