Revert "Restarting cgminer from within after ADL has been corrupted only leads to a crash. Display a warning only and disable fanspeed monitoring."

This reverts commit 07212db106a1cc654affe3b95bf8acff7b8ed752.

Reverting this did not fix the crashes people were having with ADL failing after a week and removed the functionality this patch originally intended.
