raw-posix: fix bdrv_aio_ioctl
When the raw-posix aio=thread code was moved from posix-aio-compat.c
to block/raw-posix.c, there was an unintended change to the ioctl code.
The code used to return the ioctl command, which posix_aio_read()
would later morph into a zero. This hack is not necessary anymore,
and in fact breaks scsi-generic (which expects a zero return code).
Remove it.
