markers: add an if(0) to __mark_check_format()
Wrap __mark_check_format() into an if(0) to make sure that parameters such as
trace_mark(mm_page_alloc, "order %u pfn %lu", order, page?page_to_pfn(page):0);
(where page_to_pfn() has side-effects) won't generate code because of the
__mark_check_format().
Thanks to Jan Kiszka for reporting this.
