ALSA: ice1724 - Make call to set hw params succeed on ESI Juli@

If two streams are started immediately after one another (such as a playback and a recording stream), the call to set hw params fails with EBUSY. This patch makes the call succeed, so playback and recording will work properly. Signed-off-by: David Henningsson <[email protected]> Signed-off-by: Takashi Iwai <[email protected]>
