[RFC,v3,4/5] spapr: simplify spapr_numa_associativity_init params

Commit Message

When spapr_numa_associativity_init() was introduced it was being
called from spapr_machine_init(), where we have pointers to a
SpaprMachineState and a MachineState. Having both being passed
as params spared us from calling a macro to get the MachineState.

Previous patches moved the function away from spapr_machine_init(),
and the new locations doesn't have a pointer to MachineState ready.
This resulted in  MACHINE(spapr) macro calls as the second parameter
in both callers.

Simplify the function by folding the 'MACHINE(spapr)' macro into the
function body, which can now receive only a pointer to
SpaprMachineState.
