EDAC: Fix used after kfree() error in edac_unregister_sysfs()
Code flow looks like this:
device_unregister(&mci->dev);
-> kobject_put+0x25/0x50
-> kobject_cleanup+0x77/0x190
-> device_release+0x32/0xa0
-> mci_attr_release+0x36/0x70
-> kfree(mci);
bus_unregister(mci->bus);
Fix is to grab a local copy of "mci->bus" and use that when we call
bus_unregister().
