bdevperf: Fix the period performance print info data.

Browse Source 
This patch does the following things:

1 Set the time period 1 second into a global variable,
then if we modify that value, we will make sure that
we change it in the whole file.

2 Fix the period performance printing data . We should not pass
the time period, but we should pass time period * times, since
I/Os completed are caculated from the beginning.
