Bug description:
  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.
  Upstream-ID:   c9066bf5497300db5e0ba11bf111683ea225d8c8
                 b7f1977d3f9332f82e7f388fb18076b89b83944e

  Component:     s390-tools 2.14

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