ndisc: ndisc_send_redirect() must use dev_get_by_index_rcu()

[ Upstream commit 48145a57d4 ]

ndisc_send_redirect() is called under RCU protection, not RTNL.

It must use dev_get_by_index_rcu() instead of __dev_get_by_index()

Fixes: 2f17becfbe ("vrf: check the original netdevice for generating redirect")
