Issue:
proxmox_kvm: Creating VM on ZFS store fails
### Summary

I'm trying to create a new Proxmox VM (or ensure that it exists) using Ansible. The target Proxmox instance uses ZFS to store disks/isos/dumps etc. VM creation fails because device info string for ZFS-devices appears to be getting parsed incorrectly (see traceback below).

### Issue Type

Bug Report

### Component Name

proxmox_kvm

### Ansible Version

```
$ ansible --version
ansible 2.10.8
  config file = None
  configured module search path = ['/home/anupc/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python3/dist-packages/ansible
  executable location = /usr/bin/ansible
  python version = 3.9.2 (default, Feb 28 2021, 17:03:44) [GCC 10.2.1 20210110]
```


### Configuration

```console (paste below)
$ ansible-config dump --only-changed
```


### OS / Environment

Target OS: Proxmox VE

```
# uname -a
Linux bigpve 5.4.106-1-pve #1 SMP PVE 5.4.106-1 (Fri, 19 Mar 2021 11:08:47 +0100) x86_64 GNU/Linux
# cat /etc/debian_version 
10.9
```

### Steps to Reproduce

```
$ cat vms.yml 
---
- name: Deploy VMs
  hosts: bigpve

  tasks:
  - name: Create new minimal VM
    community.general.proxmox_kvm:
      api_user: root@pam
      api_password: "<redacted>"
      api_host: bigpve
      name: testvm
      node: bigpve
      proxmox_default_behavior: no_defaults
      vmid: 1001
      scsihw: virtio-scsi-pci
      scsi:
        scsi0: "local-zfs:vm-1001-disk-0"
      net:
        net0: 'virtio,bridge=vmbr0'
      bootdisk: scsi0
```


### Expected Results

Expected task to complete successfully with a new VM created.

### Actual Results

A VM is created which appears to have all the right parameters set. But the task fails with the following output while trying to process VM info:

}
```

This prevents any subsequent tasks in the playbook from running.

Rerunning the playbook after the VM has been created doesn't cause any error.
