net: ipv4: fix rcu lockdep splat due to wrong annotation
syzbot triggered following splat when strict netlink
validation is enabled:
net/ipv4/devinet.c:1766 suspicious rcu_dereference_check() usage!
This occurs because we hold RTNL mutex, but no rcu read lock.
The second call site holds both, so just switch to the _rtnl variant.
