s390: Allow vmalloc target buffers for copy_from_oldmem()
Currently copy_from_oldmem() is not able to copy to virtual memory.
When using kexec pre-allocated ELF header, copy_from_oldmem()
is used to copy the ELF notes information to vmalloc buffers.
So fix this and use the new function copy_from_realmem() that allows
copying also to vmalloc memory.
