powerpc/powernv/eeh/npu: Fix uninitialized variables in opal_pci_eeh_freeze_status
The current implementation of the OPAL_PCI_EEH_FREEZE_STATUS call in
skiboot's NPU driver does not touch the pci_error_type parameter so
it might have garbage but the powernv code analyzes it nevertheless.
This initializes pcierr and fstate to zero in all call sites.
