ASoC: sti: Fix deadlock via snd_pcm_stop_xrun() call

This is essentially a revert of the commit dc865fb ("ASoC: sti:
Use snd_pcm_stop_xrun() helper"), which converted the manual
snd_pcm_stop() calls with snd_pcm_stop_xrun().

The commit above introduced a deadlock as snd_pcm_stop_xrun() itself
takes the PCM stream lock while the caller already holds it.  Since
the conversion was done only for consistency reason and the open-call
with snd_pcm_stop() to the XRUN state is a correct usage, let's revert
the commit back as the fix.
