====================
net: shaper: follow ups to recent fixes

As discussed previously on the patch set with real fixes the xa_locking

The remaining three patches are an attempt to silence AI reviewers,
I believe Sashiko was complaining about these non-issues. Not adding
Reported tags since these are false positives.
