Avoid Crashes when Parsing IPMI Event Log

[luckylinux]

In case there are Events Logged in the IPMI Event Log, there is a chance that, depending on the Event Type (e.g. "Intrusion Switch" or "Power ON" etc) the Script might Crash because the Field it's expecting doesn't Exist in the CSV Output of IPMItool.

Probably need to add some try and except Blocks.

Implemented basic Fix by encapsulating the whole IPMI Event Log Reading in try / except Block as part of another Commit:
