ipmr: Convert ipmr_rtm_dumplink() to RCU.
net->ipv4.mr_tables is updated under RTNL and can be read
safely under RCU.
Once created, the multicast route tables are not removed
until netns dismantle.
ipmr_rtm_dumplink() does not need RTNL protection for
ipmr_for_each_table() and ipmr_fill_table() if RCU is held.
Even if mrt->maxvif changes concurrently, ipmr_fill_vif()
returns true to continue dumping the next table.
Let's convert it to RCU.
