[PATCH 2/2] fadump: Disable deferred page struct initialisation

[Srikar Dronamraju]

Fadump kernel reserves significant number of memory blocks. On a multi-node
machine, with CONFIG_DEFFERRED_STRUCT_PAGE support, fadump kernel fails to
boot. Fix this by disabling deferred page struct initialisation.
