kernel-device: ID_USB_INTERFACE_NUM should be read as an hex string

Browse Source 
The original g_udev_device_get_property_as_int() uses strtol() without
an explicit base (i.e. 0) so that the base is autodetected from the
string whenever possible (e.g. if prefixes with '0x' it is treated as a
hexadecimal string).

But, for ID_USB_INTERFACE_NUM, we explicitly require reading the number
as an hex string, even if we don't have any '0x' prefix.
