3.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mathias Krause <mini...@googlemail.com>
[ Upstream commit e3ac104d41a97b42316915020ba228c505447d21 ]
The ESN replay window was already fully initialized in
xfrm_alloc_replay_state_esn(). No need to copy it again.
