This patch promotes the per-queue stats API to stable.
The API has been used by the Vhost PMD since v22.07, and
David Marchand posted a patch to make use of it in next
OVS release[0].

When the packet receiving failure and the DMA ring full occur
simultaneously in the asynchronous vhost, the slot_idx needs to be
decreased by 1. For packed virtqueue, the slot index should be
ring_size - 1, if the slot_idx is currently 0, since the ring size is
not necessarily the power of 2.

When vhost receive packets from the front-end using packed virtqueue, it
might use multiple descriptors for one packet, so we need calculate and
record the descriptor number for each packet to update available
descriptor counter and used descriptor counter, and rollback when DMA

Vhost-user library locks all VQ's access lock when processing
vring based messages, such as SET_VRING_KICK and SET_VRING_CALL,
and the data processing thread may already be started, e.g: SPDK
vhost-blk and vhost-scsi will start the data processing thread
when one vring is ready, then deadlock may happen when SPDK is
posting interrupts to VM. Here, we add a new API which allows
caller to try again later for this case.
