ipv6: Fix suspicious RCU usage warning in ip6mr
This patch fixes the following warning:
=============================
WARNING: suspicious RCU usage
5.7.0-rc4-next-20200507-syzkaller #0 Not tainted
-----------------------------
net/ipv6/ip6mr.c:124 RCU-list traversed in non-reader section!!
ipmr_new_table() returns an existing table, but there is no table at
init. Therefore the condition: either holding rtnl or the list is empty
is used.
Fixes: d1db275dd3f6e ("ipv6: ip6mr: support multiple tables")
