[LTP] [PATCH] aio_return: Remove cases and refactor 4-1.c

[Yang Xu <xuyang2018.jy@cn.fujitsu.com>]

Hi


>  From aio_return(3) manpage, the aio_return() function returns the
> final return status for the asynchronous I/O request with control
> block pointed to by aiocbp. It should be called only once for any
> given request. If we want to call twice for same aiocbp, it only
> returns the last value. It doesn't make sense. So remove 2-1.c and
> 3-2.c.
> 
> For 4-1.c, it failed with the same reason. But we can refactor this
> , firstly call aio_return(&aiocb2) and then call aio_return(&aiocb).
> It tests whether value override.

Here should be aio_error(&aiocb2). Sorry.
