The PHB diag-data is important to help locating the root cause for EEH errors such as frozen PE or fenced PHB. However, the EEH core enables IO path by clearing part of HW registers before collecting this data causing it to be corrupted. This patch fixes this by dumping the PHB diag-data immediately when frozen/fenced state on PE or PHB is detected for the first time in eeh_ops::get_state() or next_error() backend.
