Olivier Moysan 7835b07257 ASoC: stm32: spdifrx: fix race condition in irq handler 
commit 86e1956af4c863d653136fd6e5694adf2054dbaa upstream.

When snd_pcm_stop() is called in interrupt routine,
substream context may have already been released.
Add protection on substream context.

Fixes: 03e4d5d56f ("ASoC: stm32: Add SPDIFRX support")
