Peter Ujfalusi e3ae00ee23 ASoC: SOF: ipc4-topology: Fix input format query of process modules without base extension
commit ffa077b2f6ad124ec3d23fbddc5e4b0ff2647af8 upstream.

If a process module does not have base config extension then the same
format applies to all of it's inputs and the process->base_config_ext is
NULL, causing NULL dereference when specifically crafted topology and
sequences used.
