pci: fix unterminated pci_device_id lists

mainline: 248bdd5efca5a113cbf443a993c69e53d370236b

Fix a couple drivers that do not correctly terminate their pci_device_id
lists.  This results in garbage being spewed into modules.pcimap when the
module happens to not have 28 NULL bytes following the table, and/or the
last PCI ID is actually truncated from the table when calculating the
modules.alias PCI aliases, cause those unfortunate device IDs to not
auto-load.
