scsi: stex: Fix reboot_notifier leak in probe error path

Browse Source 
In stex_probe(), register_reboot_notifier() is called at the beginning,
but if any subsequent initialization step fails, the function returns
without unregistering the notifier, resulting in a resource leak.

Add unregister_reboot_notifier() in the out_disable error path to ensure
proper cleanup on all failure paths.
