From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
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")
