[PATCH] virsh vcpupin guards CPU not existing.

[Masayuki Sunou <fj1826dm@xxxxxxxxxxxxxxxxx>]

Hi

When CPU not existing is set to virsh vcpupin, CPU affinity is set to all CPU.

--------------------------------------------------------------------------------
# virsh vcpuinfo 0
VCPU:           0
CPU:            0
State:          blocked
CPU time:       428.8s
CPU Affinity:   y-

# virsh vcpupin 0 0 100
libvir: Xen error : failed Xen syscall  ioctl  -1208339792

# virsh vcpuinfo 0
VCPU:           0
CPU:            0
State:          blocked
CPU time:       429.6s
CPU Affinity:   yy
--------------------------------------------------------------------------------

This patch returns an error, when CPU not existing is set to virsh vcpupin.

--------------------------------------------------------------------------------
# virsh vcpupin 0 0 100
error: Physical CPU 100 doesn't exist.
