page fault on virtual bus

[Martin Schröder]

two lines should be adjusted slightly:

> local loader = L4.default_loader;
> local io_buses =
>    {
>      vbus1 = loader:new_channel();
>    };
>
>- loader:start({ caps = { client1 = vbus1:svr(),
  + loader:start({ caps = { client1 = io_buses.vbus1:svr(),
> 	                icu    = L4.Env.icu,
> 			sigma0 = L4.cast(L4.Proto.Factory, L4.Env.sigma0):create(L4.Proto.Sigma0),
> 	     }}, "rom/io rom/periTest.io");
>
>- loader:start({ caps = { vbus = vbus1 }}, "rom/periTest");
  + loader:start({ caps = { vbus = io_buses.vbus1 }}, "rom/periTest");
