PAGE_REPORTING_ORDER_UNSPECIFIED is now set to zero. This means,
pages of order zero cannot be reported to a client/driver -- as zero
is used to signal a fallback to MAX_PAGE_ORDER.

Change PAGE_REPORTING_ORDER_UNSPECIFIED to (-1),
so that zero can be used as a valid order with which pages can
be reported.
