ASoC: amd: acp: Fix possible UAF in acp_dma_open 
Smatch report warning as follows:

sound/soc/amd/acp/acp-platform.c:199 acp_dma_open() warn:
  '&stream->list' not removed from list

If snd_pcm_hw_constraint_integer() fails in acp_dma_open(),
stream will be freed, but stream->list will not be removed from
adata->stream_list, then list traversal may cause UAF.

Fix by adding the newly allocated stream to the list once it's fully
initialised.

Fixes: 7929985cfe ("ASoC: amd: acp: Initialize list to store acp_stream during pcm_open")
