Borislav Petkov bb31b3122c EDAC: Fix workqueue-related crashes 
00740c5854 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.
