[PATCH v2] tools/xl: fix channel configuration setting

[Juergen Gross <jgross@xxxxxxxx>]

Channels work differently than other device types: their devid should
be -1 initially in order to distinguish them from the primary console
which has the devid of 0.

So when parsing the channel configuration, use
ARRAY_EXTEND_INIT_NODEVID() in order to avoid overwriting the devid
set by libxl_device_channel_init().
