In some cases when delegated hosts are used with connection plugins and variables are used in the ansible_host var, they can be resolved using the wrong node (the source of the delegated task, rather than the target of the delegated task), causing the connection plugin to run all of the mysql restarts on the same host, rather than delegating to the correct ansible_host. This minor fix improves compatibility in these situations so that ansible_host is set to the correct host, causing the task to run against the correct node.
