numa: conf: Tweak parameters of virDomainNumatuneSet

As virDomainNumatuneSet now doesn't allocate the virDomainNuma object
any longer it's not necessary to pass the pointer to a pointer to store
the object as it will not change any longer.

While touching the parameter definitions I've also changed the name of
the parameter to "numa".
