[PATCH 2/2] virnuma: Annotate some functions as VIR_OPTNONE

[Michal Privoznik]

Use newly introduced VIR_OPTNONE to stop clang from optimizing
our code so much that it ends up doing something else than it's
supposed to do.

The chosen functions are "random", until qemuxml2argvtest stops
failing (modulo one test case which uses virNumaCPUSetToNodeset()
and no matter what clang ignores optnone request).
