hw/xen: Fix errp handling in xen_console

When attempting to read the 'output' node, interpret any error *other*
than ENOENT as a fatal error. For ENOENT, fall back to serial_hd() to
find a character device, or create a null device.

Do not attempt to prepend to errp when serial_hd() fails; the error
isn't relevant (and prior to this change, wasn't set anyway).
