[PATCH nvme-cli 0/2] add "State" field in command "nvme list"

[Sagi Grimberg]

> When NVMe Subsystem is connected with one or more controllers via fabric, such as NVMe-oF over RDMA,
> if some links are down, some nvme disks on the host are faulty and they won't be deleted immediately.
> But the "nvme list" command does not show these faulty disks.
> So add "State" field  in command "nvme list", and display the status of each disk for users.
> For example:
> [root at localhost nvme-cli]# nvme list
> Node        SN                   Model         Namespace Usage                    Format           FW Rev   Status

State is too generic, Maybe "Path Access" or something?
The point here is to provide general feedback for the user to go and
look in nvme list-subsys?
