edac_core: Don't let free(mci) happen while using it
A very nasty bug were happening on edac core, due to the way mci objects are
freed. mci memory is freed when kobject count reaches zero, by
edac_mci_control_release(). However, from the logs, this is clearly happening
before the final usage of mci struct:
