net, ip6_tunnel: fix namespaces move 

[ Upstream commit 5311a69aac ]

in the same manner as commit d0f4185160 ("net, ip_tunnel: fix
namespaces move"), fix namespace moving as it was broken since commit
8d79266bc4 ("ip6_tunnel: add collect_md mode to IPv6 tunnel"), but for
ipv6 this time; there is no reason to keep it for ip6_tunnel.

Fixes: 8d79266bc4 ("ip6_tunnel: add collect_md mode to IPv6 tunnel")
