There's no need to handle complicated scenarios or debug log when
filtering blocks that have already been identified as invalid. Simplify
by adding an edid_block_valid() helper that operates on const data and
prints nothing.
(Finally, here's the justification for the previously added separate
edid_block_status_valid() function!)
