[PATCH] ASoC: soc-pcm: add a check for unsupported commands to the soc_pcm_trigger

[xuhanwu <2433926602@xxxxxx>]

Dear broonie

Issue: Before and after Linux version 6.2, when the cmd is 
SNDRV_PCM_TRIGGER_DRAIN, calling the function soc_pcm_trigger results 
in different return values.
Through your guidance, I've realized that the code logic has been adjusted. 
I will further deepen my study of the code. Thank you for your guidance.

Thank you for your help.
