[PATCH for-5.2 v2 3/9] pc-bios/s390-ccw: Introduce ENODEV define and remove guards of others

[Thomas Huth]

Remove the "#ifndef E..." guards from the defines here - the header
guard S390_CCW_H at the top of the file should avoid double definition,
and if the error code is defined in a different file already, we're in
trouble anyway, then it's better to see the error at compile time instead
of hunting weird behavior during runtime later.
Also define ENODEV - we will use this in a later patch.
