ipv6: Fix NULL pointer dereference with time-wait sockets
Commit b2f5e7cd3dee2ed721bf0675e1a1ddebb849aee6
(ipv6: Fix conflict resolutions during ipv6 binding)
introduced a regression where time-wait sockets were
not treated correctly. This resulted in the following:
BUG: unable to handle kernel NULL pointer dereference at 0000000000000062
