ASoC: topology: Do not ignore route checks when parsing graphs

Browse source 
One of the framework responsibilities is to ensure that the enumerated
DPCMs are valid i.e.: a valid BE is connected to a valid FE DAI. While
the are checks in soc-core.c and soc-pcm.c that verify this, a component
driver may attempt to workaround this by loading an invalid graph
through the topology file.

Be strict and fail topology loading when invalid graph is encountered.
