[PATCH 2/3] hv_balloon: Change default page reporting order

[Yuvraj Sakshith]

page_reporting_order used to fall back to default
value (passed as parameter or MAX_PAGE_ORDER) if
the driver wishes to not provide it.

The way the driver used to do this was by passing
the order as zero.

Now that zero is a valid order that can be passed by
a driver to page reporting, we use -1 to signal
default value to be used.
