From: Rahul Bhattacharjee <quic_rbhattac@xxxxxxxxxxx> [ Upstream commit ed3725e15a154ebebf44e0c34806c57525483f92 ] qmi_msg_handler is required to be null terminated by QMI module. There might be a case where a handler for a msg id is not present in the handlers array which can lead to infinite loop while searching the handler and therefore out of bound access in qmi_invoke_handler(). Hence update the initialization in qmi_msg_handler data structure.
