Subject: [PATCH 2 of 5] IPv6: only update the lifetime of the relevant
	temporary address

IPv6: only update the lifetime of the relevant temporary address

When receiving a prefix information from a routeur, only update the lifetimes
of the temporary address associated with that prefix.
Otherwise if one deprecated prefix is advertized, all your temporary addresses
will become deprecated.
