[wasm] Fix a typo in wasm-js.cc

I guess that a comparison with i::wasm::kV8MaxWasmTableSize was not
intended here. I did not add a test because I do not even know if it is
even possible to create a WasmMemoryObject with
maximum_pages > i::wasm::kV8MaxWasmMemoryPages. Maybe we should replace
the condition with a Check instead.
