net/sched: taprio: replace safety precautions with comments

Browse source

[ Upstream commit 2c08a4f898 ]

The WARN_ON_ONCE() checks introduced in commit 13511704f8 ("net:
taprio offload: enforce qdisc to netdev queue mapping") take a small
toll on performance, but otherwise, the conditions are never expected to
happen. Replace them with comments, such that the information is still
conveyed to developers.
