[PATCH 09/17] stat: use enum fio_ddir consistently

[Niklas Cassel <Niklas.Cassel@xxxxxxx>]

From: Niklas Cassel <niklas.cassel@xxxxxxx>

Most functions in stat.c uses enum fio_ddir dir both as a parameter
and as a local variable in functions.

int ddir is used in a very few places.

Convert the int ddir uses to enum fio_ddir dir so that the code is
consistent.
