mm/memory-failure: use helper llist_for_each_entry()

Browse Source 
Change the llist_for_each_entry_safe function to the llist_for_each_entry
function and delete the next variable.  Because the linked list is not
modified,the llist_for_each_entry_safe function is not required.  No
functional changes are intended.
