ipc: check type before freeing

When freeing we currently implicitly are trusting the ID to match the
type specified in the message. From a security standpoint this is wrong,
never trust the other side. This is the likely cause of how the fuzzer
is leaking memory in pipelines since they have additional allocations
that are not freed when they are treated as a buffer or a component.
