[S390] cpcmd with vmalloc addresses.
Change the bounce buffer logic of cpcmd. diag8 needs _real_ memory below 2GB. Therefore vmalloced data does not work. As the data might cross a page boundary, we cannot use virt_to_page either. The solution is to use virt_to_page only in the check for a bounce buffer. There was a redundant check for response==NULL. response < 2GB contains this check as well. I also removed the rlen==0 check, since rlen=0 and response!=NULL would be a caller bug and response==NULL is already checked.
