commit 2704c9a5593f4a47620c12dad78838ca62b52f48 upstream. The xen_hvc_init() function should always register the frontend driver, even when there's no primary console — as there may be secondary consoles. (Qemu can always add secondary consoles, but only the toolstack can add the primary because it's special.)
