misc/pvpanic-pci: register attributes via pci_driver

In __pci_register_driver(), the pci core overwrites the dev_groups field of
the embedded struct device_driver with the dev_groups from the outer
struct pci_driver unconditionally.

Set dev_groups in the pci_driver to make sure it is used.

This was broken since the introduction of pvpanic-pci.
