Use list_for_each_entry() helper instead of explicit combo of
list_for_each() and list_entry().
Note that pos is used as a reference point in list_add_tail() in
icom_alloc_adapter(). This functionality remains as with an empty list,
cur_adapter_entry->icom_adapter_entry is still the list head.
This simplifies the code a bit.
