Make mlxcontrol work with more than one system drive:

- When searching for the next system drive, return the next one instead
  of always returning the first one.
- Plug fd lead and make sure that the MLX_NEXT_CHILD ioctl is called
  on the controller fd, not the disk's one.

While there, fix a cut-n-pase error in a warning.
