drivers/edac: fix workq reset deadlock

Fix mutex locking deadlock on the device controller linked list.  Was calling
a lock then a function that could call the same lock.  Moved the cancel workq
function to outside the lock

Added some short circuit logic in the workq code

Added comments of description
