[PATCH] Fix the check of <cpumap> in virsh vcpupin

[Masayuki Sunou <fj1826dm@xxxxxxxxxxxxxxxxx>]

Hi

Because virsh vcpupin does not check a form of <cpumap>,
when non-numerical letters are set, it does not become an error.

This patch fixes it so that it become an error when non-numerical
letters are set.

Thanks,
Masayuki Sunou.
