EDAC: Don't try to cancel workqueue when it's never setup
We only setup a workqueue for edac devices that use the polling
method. We still try to cancel the workqueue if an edac_device
uses the irq method though. This causes a warning from debug
objects when we remove an edac device:

Fix it by skipping the workqueue teardown for such devices.
