aio: prevent double free in ioctx_alloc
commit d558023207e008a4476a3b7bb8706b2a2bf5d84f upstream.
ioctx_alloc() calls aio_setup_ring() to allocate a ring. If aio_setup_ring()
fails to do so it would call aio_free_ring() before returning, but
ioctx_alloc() would call aio_free_ring() again causing a double free of
the ring.
This is easily reproducible from userspace.
