icnss: Reject QMI server arrive if it comes without server exit



During ssr/pdr ideally, wlan platform driver should get a
server exit notification over QMI followed by server arrive
but In some cases, wlan platform driver gets server arrive
indication without prior server exit indication. So, this
change asserts the system if server arrive comes without
server exit indication.
