From: Isaku Yamahata <isaku.yamahata@xxxxxxxxx>
Annotate the KVM selftests' _no_printf() with the printf format attribute
so that the compiler can help check parameters provided to pr_debug() and
pr_info() irrespective of DEBUG and QUIET being defined.
[reinette: move attribute right after storage class, rework changelog]
