Priyalee Kushwaha bf5d008164 platform/x86: intel_telemetry_debugfs: fix oops when load/unload module
This fixes an oops found while testing load/unload of the
intel_telemetry_debugfs module. module_init uses register_pm_notifier
for PM callbacks, but unregister_pm_notifier was missing from
module_exit.
