wifi: ath11k: Fix qmi_msg_handler data structure initialization
[ 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.
