HV: debug: Check if vUART is configured in partition mode
If vUART is not configured in partition mode and we try to connect vm's console through sos_console vmid, it will trigger crash of HV. This patch check whether vUART is configured. If no, just print out "No vUART configured for xxx" and return.
