s390/startup: round down "mem" option to page boundary Make a usable value out of "mem" option once and for all. Kasan memory allocator just takes memory_end or online memory size as allocation base. If memory_end is not aligned paging structures allocated in kasan end up unaligned as well. So this change fixes potential kasan crash as well.
