ALSA: hiface: Fix M2Tech hiFace driver sampling rate change

commit 995c6a7f upstream.

Sampling rate changes after first set one are not reflected to the
hardware, while driver and ALSA think the rate has been changed.

Fix the problem by properly stopping the interface at the beginning of
prepare call, allowing new rate to be set to the hardware. This keeps
the hardware in sync with the driver.
