ipv6: Make 'addrconf_rs_timer' send Router Solicitations (and re-arm itself) if Router Advertisements are accepted
As of 026359b
[ipv6: Send ICMPv6 RSes only when RAs are accepted],
Router Solicitations are sent whenever kernel accepts Router
Advertisements on the interface.
However, this logic isn't reflected in 'addrconf_rs_timer'.
The timer fails to issue subsequent RS messages (and fails to re-arm
itself) if forwarding is enabled and the special hybrid mode is
enabled (accept_ra=2).
Fix the condition determining whether next RS should be sent, by using
'ipv6_accept_ra()'.
