From: Stefano Garzarella <sgarzare@redhat.com>

When the backing_file is specified as a JSON object, the
qemu_gluster_reopen_prepare() fails with this message:
    invalid URI json:{"server.0.host": ...}

In this case, we should call qemu_gluster_init() using the QDict
'state->options' that contains the JSON parameters already parsed.
