[PATCH]util: Refresh virHook before checking its existence

[Chen Hanxiao <chenhanxiao@xxxxxxxxxxxxxx>]

From: Chen Hanxiao <chenhanxiao@xxxxxxxxxxxxxx>

We refresh the status of hook scripts
only when start/stop libvirt, or reload its configuration.
But the status of hooks scripts may be changed.
We need to refresh its status before checking its existence.
