x86 EDAC, sb_edac.c: Repair damage introduced when "fixing" channel address

Browse source

commit ff15e95c82 upstream.

In commit:

  eb1af3b71f ("Fix computation of channel address")

I switched the "sck_way" variable from holding the log2 value read
from the h/w to instead be the actual number. Unfortunately it
is needed in log2 form when used to shift the address.
