list_nulls: add hlist_nulls_add_head and hlist_nulls_del
list_nulls: add hlist_nulls_add_head and hlist_nulls_del

This patch adds the hlist_nulls_add_head() function which is
based on hlist_nulls_add_head_rcu() but without the use of
rcu_assign_pointer(). It also adds hlist_nulls_del which is
exactly the same like hlist_nulls_del_rcu().
