[ 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)")
