[PATCH V2] Remove unused CONFIG_LOCKMETER functions

[Kirk True]

Take 2 on removing these unused extern functions...

I had been working on porting SGI's lockmeter to 2.6 when I chanced upon
this. I was very perplexed that it's in there since this is the only
place that it appears in the codebase (according to grep).
