[PATCH] Staging: rtl8188eu: core: Use list_for_each_entry_safe

[Srishti Sharma]

Use list_for_each_entry_safe to make the code more compact. 
Done using the following semantic patch by coccinelle.

@r@
struct list_head* l;
expression e;
identifier m, list_del_init, f;
type T1;
T1* pos;
iterator name list_for_each_entry_safe;
@@

f(...){

+T1* tmp;
<+...
-while(...)
+list_for_each_entry_safe(pos,tmp,l,m)
{
...
-pos = container_of(l,T1,m);
...
-l=e;
 <+...
  list_del_init(&pos->m)
 ...+>
}
...+>
}
