Fwiw, this isn't cross-release but us reloading the module many times,
creating a whole host of new lockclasses. Even more fun is when the
module gets a slightly different address and the new lock address hashes
into an old lock...

I did think about a module-hook to revoke the stale lockclasses, but
that still leaves all the hashed chains.

This particular nuisance was temporarily pushed back by teaching igt not
to reload i915.ko on a whim.
