EDAC/igen6: Fix call trace due to missing release()

When unloading the igen6_edac driver, there is a call trace:

Device '(null)' does not have a release() function, it is broken and must be fixed. See Documentation/core-api/kobject.rst. WARNING: drivers/base/core.c:2567 at device_release+0x84/0x90, CPU#5: rmmod/127209 ... RIP: 0010:device_release+0x84/0x90 Call Trace: <TASK> kobject_put+0x8c/0x220 put_device+0x17/0x30 igen6_unregister_mcis+0xa2/0xe0 [igen6_edac] igen6_remove+0x82/0xb0 [igen6_edac] ...

Fix the call trace by providing empty release() functions for the memory controller devices.
