This patch factors out the vCPU count retrieval including fallback means
into vshCPUCountCollect() and removes the duplicated code to retrieve
individual counts.
The --current flag (this flag is assumed by default) now works also with
--maximum or --active without the need to explicitly specify the state
of the domain that is requested.
This patch also fixes the output of "virsh vcpucount domain" on inactive
domains:
Before:
$ virsh vcpucount domain
maximum config 4
error: Requested operation is not valid: domain is not running
current config 4
error: Requested operation is not valid: domain is not running
After:
$virsh vcpucount domain
maximum config 4
current config 4
.. and for transient domains too:
Before:
$ virsh vcpucount transient-domain
error: Requested operation is not valid: cannot change persistent config of a transient domain
maximum live 3
error: Requested operation is not valid: cannot change persistent config of a transient domain
current live 1
After:
$ virsh vcpucount transient-domain
maximum live 3
current live 1
