ipmr: Fix RCU list debugging warning
ipmr_for_each_table() macro uses list_for_each_entry_rcu()
for traversing outside of an RCU read side critical section
but under the protection of rtnl_mutex. Hence, add the
corresponding lockdep expression to silence the following
false-positive warning at boot:
[ 4.319347] =============================
[ 4.319349] WARNING: suspicious RCU usage
[ 4.319351] 5.5.4-stable #17 Tainted: G E
[ 4.319352] -----------------------------
[ 4.319354] net/ipv4/ipmr.c:1757 RCU-list traversed in non-reader section!!
Fixes: f0ad0860d01e ("ipv4: ipmr: support multiple tables")
