i7core_edac: properly terminate pci_dev_table
At pci_xeon_fixup(), it waits for a null-terminated table, while at i7core_get_all_devices, it just do a for 0..ARRAY_SIZE. As other tables are zero-terminated, change it to be terminate with 0 as well, and fixes a bug where it may be running out of the table elements.
