[PATCH v4 5/5] mm/page_reporting: change page_reporting_order to PAGE_REPORTING_ORDER_UNSPECIFIED

[Yuvraj Sakshith <yuvraj.sakshith@oss.qualcomm.com>]

page_reporting_order when uninitialised, holds a magic number -1.

Since we now maintain PAGE_REPORTING_ORDER_UNSPECIFIED as -1, which
is also a flag, set page_reporting_order to this flag.
