[PATCH] powerpc/powernv: Fix BE PE number to opal_pci_eeh_freeze_clear()

The PE number (@frozen_pe_no), filled by opal_pci_next_error() is
in big-endian format. Frozen PE number in CPU-endian should be passed
to opal_pci_eeh_freeze_clear() when clearing the frozen state if the
PE is invalid one.

This passes CPU-endian PE number to opal_pci_eeh_freeze_clear() and
it should be part of commit <0f36db77643b> ("powerpc/eeh: Fix wrong
printed PE number").
