[ALSA] hda-intel - Fix detection of audio codec on Toshiba A100 

Some boards have the audio codec on slot #3 while the modem codec
on slot #0.  The driver should continue to probe the slots when
no audio codec is found.
This fixes the problem of no device on Toshiba A100 (and some other
ATI SB450 devices).
