[PATCH] i40evf: remove redundant array comparisons to 0 checks

[Colin King]

From: Colin Ian King <colin.k...@canonical.com>

The checks to see if key->dst.s6_addr and key->src.s6_addr are null
pointers are redundant because these are constant size arrays and
so the checks always return true.  Fix this by removing the redundant
checks.

Detected by CoverityScan, CID#1465279 ("Array compared to 0")
