Subject: [PATCH] i40evf: fix 32 bit build warnings

Jesse Brandeburg fixed a bug for 32-bit systems in the i40e driver
in commit 9c70d7cebfec5 ("i40e: fix 32 bit build warnings"), but the
same code still exists in the i40evf driver and causes compilation
warnings in ARM and x86 allmodconfig:

drivers/net/ethernet/intel/i40evf/i40e_common.c:445:68: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
drivers/net/ethernet/intel/i40evf/i40e_common.c:446:71: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]

This applies the same fix by removing the broken code.

It would probably be a good idea to merge some of the duplicate code into
a library module that gets used by both drivers to avoid having to fix bugs
twice in the future.
