When out of memory and we can't add ctrl vq buffers,
probe fails. Unfortunately the error handling is
out of spec: it calls del_vqs without bothering
to reset the device first.
To fix, call the full cleanup function in this case.

Will make it reusable for error handling.

We now cleanup all VQs on device removal - no need
to handle the control VQ specially.

Console driver is out of spec. The spec says:
A driver MUST NOT decrement the available idx on a live
virtqueue (ie. there is no way to “unexpose” buffers).
and it does exactly that by trying to detach unused buffers
without doing a device reset first.
Defer detaching the buffers until device unplug.
Of course this means we might get an interrupt for
a vq without an attached port now. Handle that by
discarding the consumed buffer.

For cleanup it's helpful to be able to simply scan all vqs and discard
all data. Add an iterator to do that.

an allocated buffer doesn't need to be tied to a vq -
only vq->vdev is ever used. Pass the function the
just what it needs - the vdev.

This reverts commit 37c7c6c76d431dd7ef9c29d95f6052bd425f004c.
Turns out some drivers(most are FC drivers) may not use managed
IRQ affinity, and has their customized .map_queues meantime, so
still keep this code for avoiding regression.

It's been missing for a while but no one is touching that up. Fix it.
