Audio: SRC: Add safeguard against missing, wrong size or type init data 

In some error situations the configuration init_data may be NULL, and
in such a situations we should fail gracefully and not crash. Also adds
check that the IPC message is of correct type and for IPC3 only that it
is of correct type.
