habanalabs: add "in device creation" status
On init, the disabled state is cleared right before hw_init and that causes the device to report on "Operational" state before the device initialization is finished. Although the char device is not yet exposed to the user at this stage, the sysfs entries are exposed. This can cause errors in monitoring applications that use the sysfs entries. In order to avoid this, a new state "in device creation" is introduced to ne reported when the device is not disabled but is still in init flow.
