Subject: [PATCH] Grow: stop previous reshape process first
Git-commit: e1b942b9afa9f3310ea19c57caea896af97b557e
Patch-mainline: mdadm-4.0+
References: bsc#1069165, bsc#1069167, bsc#1068030

If array is stopped during reshape and assembled again straight away,
reshape process in a background might still be running. systemd doesn't
start a new service if one already exists. If there is a race, previous
process might terminate and new one is not created. Reshape doesn't
continue after assemble.

Tell systemd to restart the service rather than just start it. It will
assure previous service is stopped first. If it's not running, stopping
has no effect and only new process is started.
