Using ansible-pylibssh produces Unable to decode JSON from response to get_capabilities(). Received 'None'. error

##### SUMMARY
When running cisco.ios.ios_command with ansible_pylibssh, I get a JSON RPC decoding error, which I do not get when using paramiko

##### ISSUE TYPE
- Bug Report

##### PYLISSH and LIBSSH VERSION

```console
xxxx@xxxx:~$ python3 -m pip install --upgrade ansible-pylibssh
Defaulting to user installation because normal site-packages is not writeable
Requirement already satisfied: ansible-pylibssh in ./.local/lib/python3.8/site-packages (0.4.0)
```

##### STEPS TO REPRODUCE

```console
ANSIBLE VERSION:
xxxx@xxxx:~/.ssh$ ansible --version
ansible [core 2.13.1]
config file = /etc/ansible/ansible.cfg
configured module search path = ['/home/xxxx/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
ansible python module location = /home/xxxx/.local/lib/python3.8/site-packages/ansible
ansible collection location = /home/xxxx/.ansible/collections
executable location = /home/xxxx/.local/bin/ansible
python version = 3.8.10 (default, Mar 15 2022, 12:22:08) [GCC 9.4.0]
jinja version = 3.1.2
libyaml = True

```

Start with the cisco_config_verify.yml playbook and reproduce the failure using cisco.ios.ios_command with ansible_pylibssh. Compare the get_capabilities() response and JSON decoding path with the working Paramiko run. Done means the playbook completes without the decoding error when ansible_pylibssh is used.
