[S390] idle: remove idle notifier chain.
The idle notifier chain consists of at most one element. So there's no point in having a notifier chain. Remove it and directly call the function. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
