multicast: remove useless parameter for group add
Remove the mode parameter for igmp/igmp6_group_added as we can get it
from first parameter.
Fixes: 6e2059b53f988 (ipv4/igmp: init group mode as INCLUDE when join source group)
Fixes: c7ea20c9da5b9 (ipv6/mcast: init as INCLUDE when join SSM INCLUDE group)
