I'd rather remove the initial mem argument from CREATEDOMAIN, and have
the latter just allocate a domid without any actual resources.

Come to think of it, we could do away with setdominitialmem as well, and
just use setmaxmem and then MEMOP_increase_reservation (which will also
return the mfn list you were probably just about to ask for...)
