igmp: fix incorrect unsolicit report count after link down and up
After link down and up, i.e. when call ip_mc_up(), we doesn't init
im->unsolicit_count. So after igmp_timer_expire(), we will not start
timer again and only send one unsolicit report at last.
Fix it by initializing im->unsolicit_count in igmp_group_added(), so
we can respect igmp robustness value.
