[libvirt] [PATCH] storage: Need to clear pool prior to refreshPool during Autostart

[John Ferlan]

https://bugzilla.redhat.com/show_bug.cgi?id=1176510

When storageDriverAutostart is called path virStateReload via a 'service
libvirtd reload', then because the volume list in the pool wasn't cleared
prior to the call, each volume would be listed multiple times (as many
times as we reload). I believe the issue would be introduced by commit
id '9e093f0b' at least for the libvirtd reload path, although I suppose
the introduction of virStateReload (commit id '70da0494') could be a
different cause.

Thus like other places prior to calling refreshPool, we need to call
virStoragePoolObjClearVols
