[S390] Convert to smp_call_function_single.
smp_call_function_single now has the same semantics as s390's smp_call_function_on. Therefore convert to the *single variant and get rid of some architecture specific code. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
