Browse Source 
[ Upstream commit 91a46c6d1b4fcbfa4773df9421b8ad3e58088101 ]

XFRMA_REPLAY_ESN_VAL was not cloned completely from the old to the new.
Migrate this attribute during XFRMA_MSG_MIGRATE

v1->v2:
 - move curleft cloning to a separate patch

Fixes: af2f464e326e ("xfrm: Assign esn pointers when cloning a state")
