Sometimes, f2fs_io_schedule_timeout_killable(HZ) may delay for about 2
seconds, this is because __f2fs_schedule_timeout(DEFAULT_SCHEDULE_TIMEOUT)
may delay for about 2 * DEFAULT_SCHEDULE_TIMEOUT due to its precision, but
we only account the delay as DEFAULT_SCHEDULE_TIMEOUT as below, fix it.
f2fs_io_schedule_timeout_killable()
..
timeout -= DEFAULT_SCHEDULE_TIMEOUT;
