s390/stacktrace: add missing end marker
save_stack_trace() did not write the ULONG_MAX end marker if there is enough space left. So simply follow x86 and arm64. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Tested-by: Peter Oberparleiter <oberpar@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
