ipv6: set multicast flag on the multicast route 



commit ceed9038b2783d14e0422bdc6fd04f70580efb4c upstream.

The multicast route ff00::/8 is created with type RTN_UNICAST:

  $ ip -6 -d route
  unicast ::1 dev lo proto kernel scope global metric 256 pref medium
  unicast fe80::/64 dev eth0 proto kernel scope global metric 256 pref medium
  unicast ff00::/8 dev eth0 proto kernel scope global metric 256 pref medium

Set the type to RTN_MULTICAST which is more appropriate.

Fixes: e8478e80 ("net/ipv6: Save route type in rt6_info")
