edac: fix module initialization on several modules 2nd time

I implemented opstate_init() as a inline function in linux/edac.h.

added calling opstate_init() to:
	i82443bxgx_edac.c
	i82860_edac.c
	i82875p_edac.c
	i82975x_edac.c

I wrote a fixed patch of
edac-fix-module-initialization-on-several-modules.patch,
and tested building 2.6.25-rc7 with applying this. It was succeed.
I think the patch is now correct.
