ASoC: topology: Check return value for soc_tplg_pcm_create()
[ Upstream commit a3039aef52d9ffeb67e9211899cd3e8a2953a01f ]
The return value of soc_tplg_pcm_create() is currently not checked
in soc_tplg_pcm_elems_load(). If an error is to occur there, the
topology ignores it and continues loading.
Fix that by checking the status and rejecting the topology on error.
