proxmox_kvm: fix undefined local variable status (#1847)

* proxmox_kvm: undefined local variable status

* proxmox_kvm: Add a changelog fragment

* Update changelogs/fragments/1847-proxmox-kvm-fix-status.yml

Co-authored-by: Felix Fontein <felix@fontein.de>

* proxmox_kvm: fix the RETURN document

* proxmox_kvm: fix name variable when state=current

The variable name is not always defined as the module can be called with
just a vmid.

Before:

> "msg": "VM None with vmid = 118 is stopped"

After:

> "msg": "VM test-instance with vmid = 118 is stopped"
