When the vhost-vdpa device is being closed, vhost_vdpa_cleanup() doesn't
clean up the vqs pointer after free. This could lead to use-after-tree
when _compat_vdpa_reset() tries to access the vqs that are freed already.
Fix is to set vqs pointer to NULL at the end of vhost_vdpa_cleanup()

Since commit 65c7cdedeb30 ("genirq: Provide new interfaces for affinity
hints") irq_set_affinity_hint is being phased out.
Switch to new interfaces for setting and applying irq affinity hints.

This commit uses the ack() callback to determine when a buffer has been
updated, then exposes it to guest.
The current mechanism splits a dma buffer into descriptors that are
exposed to the device. This dma buffer is shared with the user
application. When the device consumes a buffer, the driver m
