xfrm: Fix xfrm_replay_overflow_offload_esn

[ Upstream commit 0ba23a211360af7b6658e4fcfc571970bbbacc55 ]

In case of wrap around, replay_esn->oseq_hi is not updated
before it is tested for it's actual value, leading function
to fail with overflow indication and packets being dropped.

This patch updates replay_esn->oseq_hi in the right place.
