i7core_edac: Introduce i7core_unregister_mci

Browse Source 
In i7core_probe, when setup of mci for 2nd or later socket failed,
we should cleanup prepared mci for 1st socket or so before "put" of
all devices.

So let have i7core_unregister_mci that can be shared between here
and i7core_remove.

While here fix a typo "hanler".
