Stephane Gasparini d57d611505 kernel/fs: fix I/O wait not accounted for RW O_DSYNC ...

When a process is doing Random Write with O_DSYNC flag
 the I/O wait are not accounted in the kernel (get_cpu_iowait_time_us).
 This is preventing the governor or the cpufreq driver to account for
 I/O wait and thus use the right pstate
