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.
