numa: Flatten simple union NumaOptions

Browse Source 
Simple unions are simpler than flat unions in the schema, but more
complicated in C and on the QMP wire: there's extra indirection in C
and extra nesting on the wire, both pointless.  They're best avoided
in new code.

NumaOptions isn't new, but it's only used internally, not in QMP.
Convert it to a flat union.
