[RFC PATCH for 4.18 5/5] rseq/selftests: cleanup: update comment above rseq_prepare_unload

From: Mathieu Desnoyers
Date: Thu Jul 05 2018 - 14:06:53 EST


rseq as it was merged does not have rseq_finish_*() in the user-space
selftests anymore. Update the rseq_prepare_unload() helper comment to
adapt to this reality.
