ipv6: Avoid unnecessary temporary addresses being generated
[ Upstream commit ecab67015ef6e3f3635551dcc9971cf363cc1cd5 ]
tmp_prefered_lft is an offset to ifp->tstamp, not now. Therefore
age needs to be added to the condition.
Age calculation in ipv6_create_tempaddr is different from the one
in addrconf_verify and doesn't consider ADDRCONF_TIMER_FUZZ_MINUS.
This can cause age in ipv6_create_tempaddr to be less than the one
in addrconf_verify and therefore unnecessary temporary address to
be generated.
Use age calculation as in addrconf_modify to avoid this.
