Use a more current logging style.

o Use pr_fmt
o Add missing newlines to formats
o Remove used-once lme_debug macro incorporating it into dbg_info
o Remove unnecessary allocation error messages
o Remove unnecessary semicolons from #defines
o Remove info macro and convert uses to pr_info
o Fix spelling of snippet
o Use %phN extension
