ip6: only honor kernel-provided RA flags if an RA was received (rh #588560)

Browse source 
The kernel apparently caches the value and will send Managed/Other flags
in the newlink message even if the router is no longer reachable and
and RA hasn't been received for a while.  So we need to make sure we
check for IF_RA_RCVD before paying attention to Managed/Other.
