edid-decode: move audio fail/warn messages

For tag 0x711, the "Audio information is present" fail message appears before
the block name. Output the block name before any fail/warning messages related
to the block.

For tags that are supposed to have an OUI but are not long enough:
- Output the block name before the "Invalid length" fail message. The fail
  message should include the block name but we don't want cta_block to output
  data_block so clear it after the fail, before exiting.

For tags with a 3 byte OUI:
- Since we are calling data_block_oui early (before data_block is output in
  cta_block), don't output block name in data_block_oui - cta_block will do
  that for us.
- data_block now includes the OUI (the block name in the failure/warning
  section will match block name in the EDID section).

Probably things would be simpler if we always set data_block to the block name,
then have fail/warning messages that don't include the block name so they don't
look redundant in the failures/warnings sections. For example we could have
something like: Unknown CTA-861 Data Block (tag 0x00): Invalid tag.
Vendor-Specific Data Block, OUI $$-$$-$$: Unknown OUI.  etc.
