constify vcpu_set_affinity()'s second parameter
None of the callers actually make use of the function's returning of
the old affinity through its second parameter, and eliminating this
capability allows some callers to no longer use a local variable here,
reducing their stack footprint significantly when building with large
NR_CPUS.
