libcamera: base: log: Remove LogInvalid check

A `LogMessage` instance cannot be moved or copied, so a severity of
`LogInvalid` is only possible if the message was constructed with that
log level explicitly. However, being a completely internal type, this
does not occur. So remove the check. And even if it does, it's probably
still better to print the message than to drop it silently.
