The case fails on routerstation(MIPS) board randomly. The root cause
is that the aio_write() calls already complete before call aio_cancel().
Fix it by increase BUF_SIZE.
Fill every struct aiocb with 0 at same time.

This case try to overflow the aio queue by call NUM_AIOCBS times
aio_read.
But for some system, the queue has no limit. So check the _SC_AIO_MAX,
if no limit then return UNSUPPORT.

Similiar with aio_read/9-1, this case try to overflow the aio queue by
call NUM_AIOCBS times aio_write.
But for some system, the queue has no limit. So check the _SC_AIO_MAX,
if no limit then return UNSUPPORT.
