net: dcb: modify dcb_app_add to take list_head ptr as parameter

In preparation to DCB rewrite. Modify dcb_app_add to take new struct
list_head * as parameter, to make the used list configurable. This is
done to allow reusing the function for adding rewrite entries to the
rewrite table, which is introduced in a later patch.
