Subject: [PATCH 4.4 32/39] xfrm: clone whole liftime_cur structure in xfrm_do_migrate

From: Antony Antony <antony.antony@...unet.com>

[ Upstream commit 8366685b2883e523f91e9816d7be371eb1144749 ]

When we clone state only add_time was cloned. It missed values like
bytes, packets.  Now clone the all members of the structure.

v1->v3:
 - use memcpy to copy the entire structure

Fixes: 80c9abaabf42 ("[XFRM]: Extension for dynamic update of endpoint address(es)")
