This reverts commit e2668ba1ed44ad56f2f1653ff5f53b277d534fac.

This commit made test 162 fail occasionally with:

The nbd server should normally terminate automatically, so trying to
kill it here now seems to cause a race that will cause a test failure
when the server terminated before the kill command has been executed.

The "Stop NBD server" patch has originally been written to solve another
problem with a hanging nbd server, but since that problem has been properly
solved by commit 3e1683485656, we now don't need the "_stop_nbd_server" here
anymore.
