When try to run lots of fsstress processes(e.g. -p 1000) always hit io_setup EAGAIN error, due to the nr_events exceeds the limit of available events. Due to each fsstress process only does once libaio read/write operation each time. So reduce the aio events number to 1, to make more fsstress processes can do AIO test.
