rxrpc: Remove rxrpc_get_reply_time() which is no longer used 



Remove rxrpc_get_reply_time() as that is no longer used now that the call
issue time is used instead of the reply time.

     This allows the timestamp on the first DATA packet of the reply of a

     successful, the timestamp will be stored into ``*_ts`` and true will be
