hw/audio/sb16: Restrict I/O sampling rate range for command 41h/42h
The I/O sampling rate range is enforced to 5000 to 45000HZ according to
commit a2cd86a9. Setting I/O sampling rate with command 41h/42h, a guest
user can break this assumption and trigger an assertion in audio_calloc
via command 0xd4. This patch restricts the I/O sampling rate range for
command 41h/42h.
Fixes: 85571bc7415 ("audio merge (malc)")
