nvme_manager: support status flag check

NVMe handler responds with incorrect raw data sometime, which
records abnormal value and triggers critical event.

Support checking "drive not ready" bit to avoid temperature reading
when NVMe is unavailable. This bit is defined in Figure 176 on page
155 of the NVMe specification.
