EDAC: Fix workqueue-related crashes
00740c58541b6087d78418cebca1fcb86dc6077d changed edac_core to un-/register a workqueue item only if a lowlevel driver supplies a polling routine. Normally, when we remove a polling low-level driver, we go and cancel all the queued work. However, the workqueue unreg happens based on the ->op_state setting, and edac_mc_del_mc() sets this to OP_OFFLINE _before_ we cancel the work item, leading to NULL ptr oops on the workqueue list. Fix it by putting the unreg stuff in proper order.
