commit 7c3a0a018e672a9723a79b128227272562300055 upstream.
Remove the assert from the callback priv lookup function since it does not require RTNL lock and is already protected by flow_indr_block_lock.
This will avoid warnings from being emitted to dmesg if the driver registers its callback after an ingress qdisc was created for a netdevice.
The warnings started after the following patch was merged: commit 74fc4f828769 ("net: Fix offloading indirect devices dependency on qdisc order creation")
