fix(dracut-logger.sh): disable SC2317 for logger functions

shellcheck 0.10 complains about SC2317 (info): Command appears to be
unreachable. Check usage (or ignore if invoked indirectly). It fails to
detect that these logger functions are called later by scripts that
source `dracut-logger.sh`. Disable shellcheck in this case.
