mei: gsc: remove unnecessary NULL pointer checks

Browse Source 
The .remove() and power management callbacks are never called unless
.probe() has already returned success, which means it has set drvdata to a
non-NULL pointer, so "dev" can never be NULL in the other callbacks.

Remove the unnecessary checks.
