Bus ids for VMBus devices in /sys/bus/vmbus/devices/ are not guaranteed to be persistent across reboot or kernel restart and this causes problems for some tools. E.g. kexec tools use these ids to identify NIC on kdump. Fix the issue by using if_instance from channel offer as the unique id instead of an auto incremented counter.
Changes since v1: - Use if_instance instead of relid [K. Y.
