Hung-Te Lin 79445817ae 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).
