cachefiles: extract ondemand info field from cachefiles_object
[ Upstream commit 3c5ecfe16e7699011c12c2d44e55437415331fa3 ]
We'll introduce a @work_struct field for @object in subsequent patches,
it will enlarge the size of @object.
As the result of that, this commit extracts ondemand info field from
@object.
