[Xen-devel] [PATCH 3/4] mm: Don't request scrubbing until dom0 is running

There is no need to scrub pages freed during dom0 construction
since heap will be scrubbed once dom0 is ready (by scrub_heap_pages()).

Since boot_scrub_done will not be set if boot-time scrubbing is off we
also check for domain state.
