stable inclusion from stable-5.10.68 commit 855c17ffa65fe61b1e3cc9164833496191dc61e1 bugzilla: 182671 https://gitee.com/openeuler/kernel/issues/I4EWUH
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
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")
