Eric Dumazet d77570ae43 ndisc: ndisc_send_redirect() must use dev_get_by_index_rcu() ...

[ Upstream commit 48145a57d4bbe3496e8e4880b23ea6b511e6e519 ]

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")
