aio_suspend/3-1: wait all aio_write complete

After aio_suspend, wait all aio_write operations to complete.

If don't do that, it fails with "Segmentation fault" on routerstation(mips)
board randomly about in 1000 continuous test. The reason may be some
aio_writes don't complete before close the file, that cause some resouse
don't be released and finally cause segment fault.
