Issue:
GetChassisPower fails to report power information when multiple chassis are present
### Summary

The `GetChassisPower` command in `redfish_info` will fail to report power for _all_ chassis if:
- multiple chassis are present
- at least one chassis does not report power information

We are encountering this on servers that have backplanes which report as a "Chassis" (but do not report power information).

Sample playbook
```
---
- hosts: all
  gather_facts: false
  vars:
    bmc_username: root
    bmc_password: hunter2
    default_uri_timeout: 50
    default_uri_retries: 5
  tasks:
  - name: Gather initial BMC lan infomration
    command: ipmitool lan print
    register: ipmitool_output
    changed_when: ipmitool_output.rc != 0
    become: true

  - name: Set BMC IP address as fact
    set_fact:
      bmc_address: "{{ ipmitool_output.stdout | regex_search('IP Address\\s+:\\s+(\\d{1,3}\\.\\d{1,3}\\.\\d{1,3}\\.\\d{1,3})', '\\1')
                                              | first }}"

  - name: Get Chassis Power
    community.general.redfish_info:
      category: Chassis
      command: GetChassisPower
      baseuri: "{{ bmc_address }}"
      username: "{{ bmc_username }}"
      password: "{{ bmc_password }}"
      timeout: "{{ default_uri_timeout }}"
    retries: "{{ default_uri_retries }}"
    register: redfish_chassis_power

  - debug:
      var: redfish_chassis_power


```
Results in:

```

```
Sample Server:

```
jyundt@prod-jump04:~$ curl -skL -u root:$BMC_PASSWORD https://10.208.9.24/redfish/v1/Chassis | jq '.'
{
  "@odata.type": "#ChassisCollection.ChassisCollection",
  "@odata.id": "/redfish/v1/Chassis",
  "Id": "Chassis",
  "Name": "Chassis Collection",
  "Members": [
    {
      "@odata.id": "/redfish/v1/Chassis/1"
    },
    {
      "@odata.id": "/redfish/v1/Chassis/NVMeSSD.0.Group.0.StorageBackplane"
    }
  ],
  "Members@odata.count": 2
}
jyundt@prod-jump04:~$ curl -skL -u root:$BMC_PASSWORD https://10.208.9.24/redfish/v1/Chassis/1/ | jq '.Power'
{
  "@odata.id": "/redfish/v1/Chassis/1/Power"
}
jyundt@prod-jump04:~$ curl -skL -u root:$BMC_PASSWORD https://10.208.9.24/redfish/v1/Chassis/NVMeSSD.0.Group.0.StorageBackplane | jq '.Power'
null
jyundt@prod-jump04:~$
```


### Expected Results

I would expect the Chassis Power to report correctly for this server and skip the backplane / Chassis that does not have Power data.

### Actual Results

```console (paste below)
