Description: zipl: Fix KVM IPL without bootindex
Symptom: Failed IPL on KVM when no bootindex is specified.
Problem: Without bootindex specified there is no IPL parmblock
               on KVM which can be read by the stage3 loader.
Solution: In case diag308 gives a response code 0x102 the stage3
               loader can safely assume that no secure IPL is required
               since no IPL report block exists.
Reproduction: IPL on KVM without 'bootindex=' attached.

Component: s390-tools 2.14

Should also be integrated into 20.04, where secure boot is enabled.
