reset osd perf counters

[Shain Miley <smiley@xxxxxxx>]

Is there a way to 'reset' the osd perf counters?

The numbers for osd 73 though osd 83 look really high compared to the 
rest of the numbers I see here.

I was wondering if I could clear the counters out, so that I have a 
fresh set of data to work with.
