ASoC: wm_adsp: Check for buffer in trigger stop
commit 43d147be5738a9ed6cfb25c285ac50d6dd5793be upstream.
Trigger stop can be called in situations where trigger start failed
and as such it can't be assumed the buffer is already attached to
the compressed stream or a NULL pointer may be dereferenced.
Fixes: 639e5eb3c7d6 ("ASoC: wm_adsp: Correct handling of compressed streams that restart")
