edid: Fix extension parsing when EDID blob does not have any extensions.

When parsing "extensions", we should skip the first EDID (main) block and start
    from offset 128 (EDID may have only main block, so an EDID without any
    extension is fine) because the header format for main block and extensions are
    different.

Without this we will see "Unknown extension block" on all EDIDs, and seeing an
    error (1) return value for EDIDs without extension.

Also, after the first "unknown" error is fixed, we can now collect all return
    values from parse_extension, and return an error when any of the extensions are
    wrong (not just last one).
