drm/tinydrm: Replace list_for_each with list_for_each_entry

Replace use of list_for_each with list_for_each_entry to simplify the
code and remove variables that are used only in list_for_each.
Done with following coccinelle patch:

@r@
identifier fn,i,f,p;
expression e;
iterator name list_for_each, list_for_each_entry;
type T;
@@

fn(...) {
++ T *i;
  <+...
- list_for_each(p,e)
+ list_for_each_entry(i,e,f)
  {
              ...
-   T *i = list_entry(p,T,f);
                  ...
   }
   ...+>
