secril-client: Fix RIL client token management in SendOemRequestHookRaw()

On some devices, like SM-T805 (Galaxy Tab S 10.5 LTE), the RIL client
code produces errors "SendOemRequestHookRaw: No token" due to large
amount of tokens allocated by OEM messages requiring no response from
RIL daemon (like set call audio path, set call volume, set mite etc).

The indicator of an OEM message with no response expected is:

     RegisterRequestCompleteHandler(client, REQ_XXX, NULL);

inside the RIL client message method. To prevent the token pool from
overflows, the proposed patch de-registers the token and frees its call
history if the handler for this message req_id is set to NULL.
