Create bus_type was just calling register_bustype. Since we control how
many times we call create_bus_type it was extraneous keeping a counter if
the bus was already registered, so the functions were no longer needed.

Adds error handling to the chipset_device_create message. If it returns
a failure, it is assumed it has not signaled the s-Par firmware of the

Add error handling to the function handle_command.
Since handle_command now returns errors, we need to process them correctly
in process_controlvm_event.
Note: It is invalid to have a controlvm test message in the event queue, so
return -EINVAL if one is discovered.
