ASoC: topology: fix memory leaks on sm, se and sbe
Currently when a kstrdup fails the error exit paths don't free
the allocations for sm, se and sbe. This can be fixed by assigning
kc[i].private_value to these before doing the ksrtdup so that the error
exit path will be able to free these objects.
Addresses-Coverity: ("Resource leak")
Fixes: 9f90af3a9952 ("ASoC: topology: Consolidate and fix asoc_tplg_dapm_widget_*_create flow")
