Allow deprecation message for power_state

[mayrstefan]

General information

It looks like NVIDIA is deprecating the power_state XML-Element in it's nvidia-smi output. We need to allow the deprecation message as a valid input when parsing the the nvidia_smi section.

Bug reports

See report in https://forum.checkmk.com/t/parsing-of-section-nvidia-smi-failed/56724)

From the crash file:

• OS: Ubuntu 22.04.5 LTS
• Checkmk version: 2.4.0p10
• Detailed steps to reproduce the bug use the attachment from the forum post:

1. create dummy host
2. use a data source program for this host with cat nvidia_smi_plugin_out.txt

Looks like nvsmi_device_v13.dtd allows a deprecation message for the power_state element: <power_state>Requested functionality has been deprecated</power_state>

This is unexpected for Checkmk which causes a crash when parsing the section.

Proposed changes

• What is the expected behavior: accept the deprecation message and proceed parsing the section
• What is the observed behavior: it crashes
• Is this a new problem? What made you submit this PR (new firmware, new device, changed device behavior)? New version of nvidia-smi cli
