[S390] cio: handle ssch() return codes correctly.
ssch() has two classes of return codes: - condition codes (0-3) which need to be translated to Linux error codes - Linux error codes (-EIO on exceptions) which should be passed to the caller (instead of erronously being handled like condition code 3) Signed-off-by: Cornelia Huck <cornelia.huck@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
