RBD Plugin: rbdStatus only check output of successful `rbd status` run

**What this PR does / why we need it**:

Current RBDUtil.rbdStatus implementation never return error in any cases, even if command not found or `rbd status` never succeed. This PR change it to only check output of successful `rbd status` run, and return error on other cases.

Because there are maybe network problem or ceph cluster unresponsive conditions which will cause `rbd status` command to fail. We cannot assume there is no watchers on given image. It's better to return error, and let the caller to decide what to do.
