[S390] Replace ENOTSUPP usage with EOPNOTSUPP
ENOTSUPP is not supposed to leak to userspace so lets just use EOPNOTSUPP everywhere. Doesn't fix a bug, but makes future reviews easier. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
