staging: r8188eu: remove dummy entries from OnAction_tbl

Unlike mlme_sta_tbl, OnAction_tbl is an array of structs.

OnAction iterates over the array to find the entry for a specific action
category. No action is performed if a category has no entry.

We can remove the entries that point to the dummy function DoReserved.
These were the last users of DoReserved, the function itself can be
removed as well.
