bdevperf: adjust the bdevperf task number.

Browse Source 
According to my analysis, the exact number is not
related with core number, which should be calucated
as g_target_count * g_queue_depth. Since each
target will be run I/O by differnet cores.

And it would solve the task number not enough issue.
