[using ioctl() AFMT_QUERY returns format == 0]

thanks! the code appears in the same file at line 1027 in 3.1-RELEASE; the
code is different in 3.2-RELEASE (line 1059), but on inspection it doesn't
look like this particular bug has been fixed--the changes fix a bug causing
ioctl() to fail on some sound cards, rather than this problem of returning
successfully with the wrong value.

I don't speak for NTT MCL. I'm an intern.
