bulk: Access existing variables initialized to &S->F when available

Browse source 
When a variable is initialized to &struct->field, use it
in place. Rationale: while this makes the code more concise,
this also helps static analyzers.

Mechanical change using the following Coccinelle spatch script:

 @@
 type S, F;
 identifier s, m, v;
 @@
      S *s;
      ...
      F *v = &s->m;
      <+...
 -    &s->m
 +    v
      ...+>
