EDAC/al_mc: Make use of the helper function devm_add_action_or_reset() 

The helper function devm_add_action_or_reset() will internally call
devm_add_action(), and if devm_add_action() fails then it will
execute the action mentioned and return the error code. So use
devm_add_action_or_reset() instead of devm_add_action() to simplify the
error handling, reduce the code.
