Adjustment of log levels in shutdown.sh

[witchessabath]

Describe the enhancement

I have noticed that users get short messages on shutdown from the shutdown script in module 99shutdown:
warn "Killing all remaining processes" and warn "Unmounted $mp."

I was wondering why these are configured with log level 'warn' since this is the expected behavior and not an error report. In dracut-ng module 86shutdown, they are set to 'info', and only problems in the shutdown process result in 'warn' messages.
Could this be adapted for dracut too?
