[PATCH 4/6] stat: reset_io_stats: fix a problem, rearrange some code

[Vincent Fu <vincentfu@gmail.com>]

From: Vincent Fu <Vincent.Fu@sandisk.com>

1) Make sure all the io_u_lat_u/m are reset
2) Only need to zero out total_submit/complete once
3) Reset total/short/drop_io_u inside the other loop that iterates over data directions
