ALSA: hda - Return the error from get_wcaps_type() for invalid NIDs
When an invalid NID is given, get_wcaps() returns zero as the error,
but get_wcaps_type() takes it as the normal value and returns a bogus
AC_WID_AUD_OUT value. This confuses the parser.
With this patch, get_wcaps_type() returns -1 when value 0 is given,
i.e. an invalid NID is passed to get_wcaps().
