powerpc/powernv: Check kzalloc() return value in pnv_pci_table_alloc

Browse source

pnv_pci_table_alloc() ignores possible failure from kzalloc_node(),
this adds a check. There are 2 callers of pnv_pci_table_alloc(),
one already checks for tbl!=NULL, this adds WARN_ON() to the other path
which only happens during boot time in IODA1 and not expected to fail.
