Subject: [PATCH net-next 6/6] i40evf: remove the boilerplate of i40evf module for init/exit

Use module_pci_driver() to simplify i40evf 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.
