From: Colin Ian King <colin.k...@canonical.com>
The use of the | operator always leads to true on the expression
(rt->rt6i_flags | RTF_CACHE) which looks rather suspect to me. I
believe this is fixed by using & instead to just check the
RTF_CACHE entry bit.
Detected by CoverityScan, CID#1457747 ("Wrong operator used")
Fixes: 35732d01fe31 ("ipv6: introduce a hash table to store dst cache")
