ip6_gre: release cached dst on tunnel removal
[ Upstream commit d4257295ba1b389c693b79de857a96e4b7cd8ac0 ]
When a tunnel is deleted, the cached dst entry should be released.
This problem may prevent the removal of a netns (seen with a x-netns IPv6
gre tunnel):
unregister_netdevice: waiting for lo to become free. Usage count = 3
