[PATCH net-next 4/6] igbvf: remove the boilerplate of igbvf module for init/exit

[PATCH net-next 4/6] igbvf: remove the boilerplate of igbvf module for init/exit

[Jean Sacren]

Use module_pci_driver() to simplify igbvf driver module init/exit
routine.

After the change, the basic driver info doesn't print unless the
pertinent hardware is present. Printing such info generally
pronounces the presence of the hardware and it should be part of the
probe routine. Blindly printing not only clutters the console, but
also incurs unnecessary confusion.
