linux-aio: Fix laio resource leak
when hotplug virtio-scsi disks using laio, the aio_nr will
increase in laio_init() by io_setup(), we can see the number by
# cat /proc/sys/fs/aio-nr
128
if the aio_nr attach the maxnum, which found from
# cat /proc/sys/fs/aio-max-nr
65536
the hotplug process will fail because of aio context leak.
Fix it by io_destroy in laio_cleanup().
