llist: add interface to check if a node is on a list.
With list.h lists, it is easy to test if a node is on a list, providing
it was initialised and that it is removed with list_del_init().
This patch provides similar functionality for llist.h lists.
init_llist_node()
marks a node as being not-on-any-list be setting the ->next pointer to
the node itself.
llist_on_list()
tests if the node is on any list.
llist_del_first_init()
remove the first element from a llist, and marks it as being off-list.
