[0/2] xen: fix/enhance temporary vcpu pinning

Message

While trying to handle temporary vcpu pinnings in a sane way in my
core scheduling series I stumbled over a bug and found a nice way to
simplify the temporary pinning cases.

I'm sending the two patches independently from my core scheduling
series as they should be considered even without core scheduling.

  xen/sched: fix locking in restore_vcpu_affinity()
  xen: merge temporary vcpu pinning scenarios
