ASoC: topology: Fix memleak in soc_tplg_manifest_load()
In case of ABI version mismatch, _manifest needs to be freed as it is just a copy of the original topology manifest. However, if a driver manifest handler is defined, that would get executed and the cleanup is never reached. Fix that by getting the return status of manifest() instead of returning directly.
