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

commit bd3c200e6d5495343c91db66d2acf1853b57a141 upstream.

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.
