s390x: Return specification exception for unimplemented diag 308 subcodes
The architecture specifies specification exceptions for all
unavailable subcodes.
The presence of subcodes is indicated by checking some query subcode.
For example 6 will indicate that 3-6 are available. So future systems
might call new subcodes to check for new features. This should not
trigger a hw error, instead we return the architectured specification
exception.
