[PATCH v2 7/7] spapr_hcall: h_home_node_associativity now reads numa_assoc_array

[Daniel Henrique Barboza <danielhb413@gmail.com>]

home_node_associativity reply now uses the associativity
values for tcpu->node_id provided by numa_assoc_array.

This will avoid further changes in this code when numa_assoc_array
changes values, but it won't be enough to prevent further changes
if (falar aqui q se mudar o tamanho do array tem q mexer nessa
funcao tambem, falar q a macro associativity() deixa a automacao
de tudo mto unreadable)
