Subject: [PATCH] i40evf: remove redundant null check on key

From: Colin Ian King <colin.king@...onical.com>

key has previously been null checked so the subsequent null check
is redundant as key can never be null at that point, so remove it.

Detected by CoverityScan, CID#1357164 ("Logically dead code")
