From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
The use of the | operator always leads to true which looks rather
suspect to me. Fix this by using & instead to just check the
RTF_CACHE entry bit.
Detected by CoverityScan, CID#1457734, #1457747 ("Wrong operator used")
Fixes: 35732d01fe31 ("ipv6: introduce a hash table to store dst cache")
