ASoC: topology: remove unused 'err'

In soc_tplg_pcm_elems_load, a variable 'err' is initialized but not
used.

It is assigned return values for pcm_new_ver() but never checked, so
remove it.

sound/soc/soc-topology.c: In function ‘soc_tplg_pcm_elems_load’:
sound/soc/soc-topology.c:1865:9: warning: variable ‘err’ set but not used [-Wunused-but-set-variable]
  int i, err;
