[ALSA] es1938 - Fix resume

Modules: ES1938 driver

This patch fixes the suspend/resume issue I'm having with ESS-Solo1
soundcard. Without this patch I might get after resume message
that kernel is disabling the IRQ5 (soundcard). If there was something
playing it wont continue after resume without this patch.
