xfrm: clone XFRMA_REPLAY_ESN_VAL in xfrm_do_migrate
[ 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")
