EDAC: Fixup scrubrate manipulation
Make the ->{get|set}_sdram_scrub_rate return the actual scrub rate bandwidth it succeeded setting and remove superfluous arg pointer used for that. A negative value returned still means that an error occurred while setting the scrubrate. Document this for future reference. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com>
