Brian King cd5aeb9f6c powerpc: Fix vio_bus_probe oops on probe error
When CMO is enabled and booted on a non CMO system and the VIO
device's probe function fails, an oops can result since
vio_cmo_bus_remove is called when it should not.  This fixes it by
avoiding the vio_cmo_bus_remove call on platforms that don't implement
CMO.
