FIO enter dead-loop to look for new file

When I used below job file to test, it hangs. I used gdb to check it and found
thread_main keeps calling clear_io_state over and over again. Every sub-process
has one file, but it doesn't finish its task after it finishs the file, so it
calls do_io again and again although it has no more file.

If change bsrange=4k-4k, it does work. if it's 2k-4k, it also doesn't work.
