xfrm: release neighbor upon dst destruction
[ Upstream commit 18cf0d0784b4a634472ed24d0d7ca1c721d93e90 ]
Neighbor is cloned in xfrm6_fill_dst but seems to never be released.
Neighbor entry should be released when XFRM6 dst entry is destroyed
in xfrm6_dst_destroy, otherwise references may be kept forever on
the device pointed by the neighbor entry.
I may not have understood all the subtleties of XFRM & dst so I would
be happy to receive comments on this patch.
