    pctrie: drop meaningless neighbor check
    
    In PCTRIE_INSERT_LOOKUP_{G,L}E, there is a test - if two pointers are
    equal, replace one with a new value. The pointers can never be equal;
    one points to a struct pctrie_node and the other is the (void*) cast
    of a pointer to a field within a struct pctrie_node. So the tests and
    assignments can be removed with no effect.
