Revert "vhost_net: start/stop guest notifiers properly" This reverts commit aad4dce934649b3a398396fc2a76f215bb194ea4. I accidentally merged the wrong version of a pull request which had a buggy version of this patch. Reverting the buggy version means we can then cleanly merge in the correct pull with the corrected change. Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
