powerpc/powernv: Use CPU-endian hub diag-data type in pnv_eeh_get_and_dump_hub_diag()
The hub diag-data type is filled with big-endian data by OPAL call
opal_pci_get_hub_diag_data(). We need convert it to CPU-endian value
before using it. The issue is reported by sparse as pointed by Michael
Ellerman:
eeh-powernv.c:1309:21: warning: restricted __be16 degrades to integer
This converts hub diag-data type to CPU-endian before using it in
pnv_eeh_get_and_dump_hub_diag().
