[Drbd-dev] [PATCH 04/10] drbd: move comment about stopping the receiver thread to where it belongs

From: Lars Ellenberg <lars.ellenberg at linbit.com>

When the last volume of a replication group is unconfigured,
the worker thread exits. To not interfere with cleanup
of other threads, before the the last cleanups run,
we need to make sure the receiver has already exited.

The commend explaining that clearly belongs above
drbd_thread_stop(&tconn->receiver), not in the cleanup loop below.
