PCI: acpiphp_ibm: Do not use uninitialized device_class

Browse Source 
Passing an uninitialized pnp.device_class string to
acpi_bus_generate_netlink_event() is effectively equivalent
to passing an empty string literal to it.

Accordingly, make the driver do the latter instead of doing the former.

No intentional functional impact.

This will facilitate the removal of device_class from struct
acpi_device_pnp in the future.
