ifdef DIAGNOSTIC in azalia.c

[Alexey Suslikov]

Hi tech@.

If there is a need to debug something in azalia.c, defining DIAGNOSTIC
is overkill so replace two instances of DIAGNOSTIC with AZALIA_DEBUG
(DPRINTF->printf suggested by ratchov@).

Also, entirely remove 3rd instance of DIAGNOSTIC. Normally it is not
compiled and, ratchov@ thinks, related to deleted code.

Okays? Comments?
