  ovn: Set router lifetime value for IPv6 periodic RA.

ovn-controller when it sends out periodic RA packets, sets '0' in the
Router lifetime field. As per the RFC 4861,  lifetime of 0 indicates that
the router is not a default router and SHOULD NOT appear on the default
router list. Without the default route, a VM will not able to reach to
other router ports attached to the same router unless a default route
is added by the user.

ovn-controller when encoding the 'put_nd_ra_opts' action sets the Router
Lifetime field to 0xffff. So this patch also sets the same value when
sending out the periodic RAs.
