  Each iLO device is allocated `max_ccb` minor device numbers (one for
each channel).  When `ilo_probe()` calls `device_create()` in a loop,
the minor device numbers passed to `device_create()` start at 0.  For
consistency with the call to `cdev_add()`, and for consistency with the
calls to `device_destroy()` from `ilo_remove()`, the minor device
numbers passed to `device_create()` should start at the value in the
variable `start`.  Fix it.

This is a logical bug rather than an actual bug, because the number of
supported devices is `MAX_ILO_DEV` which is defined as `1`.
