Subject: nfs-iostat.py: don't wait for an extra interval when given a count

nfs-iostat.py: don't wait for an extra interval when given a count

If I invoke the tool with an interval of 10 and a count of 2, it will:
- show the summary
- sleep 10s
- show the stats for the last 10s
- sleep 10s
- exit
