Subject: [PATCH 2/4] xen: remove XEN_SCRUB_PAGES in xen.config

Commit 197ecb3802c0 ("xen/balloon: add runtime control for scrubbing
ballooned out pages") changed config XEN_SCRUB_PAGES to config
XEN_SCRUB_PAGES_DEFAULT. As xen.config sets 'XEN_BALLOON=y' and
XEN_SCRUB_PAGES_DEFAULT defaults to yes, there is no further need to set
this config in the xen.config file.

Remove setting XEN_SCRUB_PAGES in xen.config, which is without
effect since the commit above anyway.
