[wasm] Avoid checking for scheduled_exceptions in the wasm deserialization

ValueDeserializer::ReadWasmModule does not call API functions, therefore
there can be no scheduled_exceptions, and therefore we do not have to
translate scheduled_exceptions to pending_exceptions. On the contrary,
there can be pending_exceptions, which causes the call to
RETURN_EXCEPTION_IF_SCHEDULED_EXCEPTION to crash.

This CL fixes a crash in a layout test which was caused by another
CL (https://crrev.com/c/975547).
