Subject: [PATCH 4/6] Staging: rtl8188eu: core: Use list_entry instead of container_of

For variables of the type struct list_head* use list_entry to access
current list element instead of using container_of. Done using the
following semantic patch by coccinelle.

@r@
struct list_head* l;
@@

-container_of
+list_entry
   (l,...)
