ipv6: drop metadata dst in ip6_route_input
The fix in commit 48fb6b554501 is incomplete, as now ip6_route_input can be
called with non-NULL dst if it's a metadata dst and the reference is leaked.
Drop the reference.
Fixes: 48fb6b554501 ("ipv6: fix crash over flow-based vxlan device")
Fixes: ee122c79d422 ("vxlan: Flow based tunneling")
