Hi,

I added Bian's following opinion to patch:
------------
  Another one should be fix like this.

	if (ret != EINVAL)
	{
-		printf(TNAME " errno is not EINVAL %s\n", strerror(errno));
+		printf(TNAME " errno is not EINVAL %s\n", strerror(ret));
		return PTS_FAIL;
	}
------------

And I added following two modifications.

 - Closing the file descriptor when exit.

 - Clear "errno".
   The first "unlink()" fails because the file doesn't exist.
   After that, ENOENT is set to "errno" and kept intact.
   I revised to clear "errno".

I noticed that there were similar problems in the other "aio-..." test programs.
But I cannot judge whether other test programs must be revised.
I revise only "aio_error/3-1".
