[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)
