s390/dump: fix old lowcore virtual vs physical address confusion
Virtual addresses of vmcore_info and os_info members are wrongly passed to copy_oldmem_kernel(), while the function expects physical address of the source. Instead, __pa() macro should have been applied. Yet, use of __pa() macro could be somehow confusing, since copy_oldmem_kernel() may treat the source as an offset, not as a direct physical address (that depens from the oldmem availability and location). Fix the virtual vs physical address confusion and make the way the old lowcore is read consistent across all sources.
