The smsdvb_module_init() returns without checking the retval from
smscore_register_hotplug().
If the smscore_register_hotplug() failed, the module failed to install,
leaving the smsdvb_debugfs not unregistered.
Fixes: 3f6b87cff66b ("[media] siano: allow showing the complete statistics via debugfs")
