i40evf: hide unused variable

On architectures with larger pages, we get a warning about an unused variable:

drivers/net/ethernet/intel/i40evf/i40evf_main.c: In function 'i40evf_configure_rx':
drivers/net/ethernet/intel/i40evf/i40evf_main.c:690:21: error: unused variable 'netdev' [-Werror=unused-variable]

This moves the declaration into the #ifdef to avoid the warning.

Fixes: dab86afd ("i40e/i40evf: Change the way we limit the maximum frame size for Rx")
