[PATCH v2] nvme-user: Minor enhancement and fixes

[Keith Busch]

It appears you broke your device.

If you see /dev/nvme0n1, you can treat it like any block handle (like
/dev/sda, for example). You shouldn't have to run an nvme format unless
that's what you really want to do, but it doesn't sound necessary given
your goal, and your device became unresponsive after.

After you fix your device, you can create a filesystem:

   # mke2fs /dev/nvme0n1

Then mount:

   # mount /dev/nvme0n1 /mnt

Adjust accordingly if you want a different filesystem or mount point.
