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

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

The null check on pointer key has already been performed at the
start of the function and this leads to a return of -EOPNOTSUPP.
The second null check on key is therefore always false, it is
redundant and can be removed.

Addresses-Coverity: ("Logically dead code")
