ipmr: Add __rcu to netns_ipv4.mrt.
kernel test robot reported this Sparse warning:
$ make C=1 net/ipv4/ipmr.o
net/ipv4/ipmr.c:312:24: error: incompatible types in comparison expression (different address spaces):
net/ipv4/ipmr.c:312:24: struct mr_table [noderef] __rcu *
net/ipv4/ipmr.c:312:24: struct mr_table *
Let's add __rcu annotation to netns_ipv4.mrt.
Fixes: b3b6babf4751 ("ipmr: Free mr_table after RCU grace period.")
