[Intel-wired-lan] [PATCH] i40e/i40evf: cleanup i40e_update_nvm_checksum()

[Dan Carpenter]

Smatch complains that we use 'checksum' when it's uninitialized.

    drivers/net/ethernet/intel/i40e/i40e_nvm.c:581 i40e_update_nvm_checksum()
    error: uninitialized symbol 'checksum'.

This is true, but it harmless because we don't use it again.
