commit 242c46c023610dbc0213fc8fb6b71eb836bc5d95 upstream.
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.
