Well I did do a grep to make sure it's safe. But yeah relying
on ip_route_connect to pass the right value through isn't nice.
[IPSEC]: Make callers of xfrm_lookup to use XFRM_LOOKUP_WAIT
This patch converts all callers of xfrm_lookup that used an
explicit value of 1 to indiciate blocking to use the new flag
XFRM_LOOKUP_WAIT.
