s390x: Return specification exception for unimplemented diag 308 subcodes

Browse Source 
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.
