pc-dimm: assign and verify the "slot" property during pre_plug

Browse source 
We can assign and verify the slot before realizing and trying to plug.
reading/writing the slot property should never fail, so let's reduce
error handling a bit by using &error_abort.

To do this during pre_plug, add and use (x86, ppc) pc_dimm_pre_plug().
