Comment 5 for bug 1804208

Seems that `_update_host_state_map` is not the only place to fix.

While creating 500 shares, the manila-scheduler log starts printing "Share service is down." several times. However, running `manila service-list` still shows the manila-share service as `up`.

But when I restart manila-share service, running `manila service-list` shows manila-share service as `down` while it's exporting its 500 shares.
