[Libvir] [PATCH] add error message for the case of the vcpupin command fails.

[Richard W.M. Jones]

OK, I'm going to qualify that a bit.  Is it always safe to access
arg->data?  I think probably it is, but I'm not sure so I modified the
patch slightly just to print an error message like this:

$ src/virsh -c test:///default vcpupin test AAA 0,1
error: vcpupin: Invalid or missing vCPU number.

Rich.

PS. Please try to attach your patches instead of pasting them inline.
