xenpaging: compare both token and path when checking for @releaseDomain event

Subsequent patches will use xenstored to store the numbers of pages
xenpaging is suppose to page-out. A domain_id value could be
misinterpreted as number of pages. Compare both path and token to
recognize the @releaseDomain event.
