llist.c: Nullify pointers after free()'ing.
* Set all data members to "NULL" in llist_free_inner() after freeing them. Altough we normally shouldn't continue working with a list that already went through llist_free_inner(), this will protect against dangling pointer bugs in case anyone will ever come up with the idea of doing so. * Set list head to "NULL" in llist_free(), basically to put the list into an initialized state.
