That’s why the ring should be in multi-producer
and single consumer mode.
Anatomic counter manages the tasks completion notification.
The threads report errors to the caller by
a dedicated error counter per task.

To speed up queue create time, event qp and cq will create only once.
Each virtq creation will reuse same event qp and cq.
Because FW will set event qp to error state during virtq destroy,
need modify event qp to RESET state, then modify qp to RTS state as
usual. This can save abo

The motivation of this change is to reduce vDPA device queue creation
time by create some queue resource in vDPA device probe stage.
In VM live migration scenario, this can reduce 0.8ms for each queue
creation, thus reduce LM network downtime.

Move rte_eal_cleanup to function vdpa_sample_quit which

Otherwise rte_eal_cleanup won't be called on receiving signal
like SIGINT(control + c).

Add device removal in function rte_eal_cleanup. This is the last chance
device remove get called for sanity. Loop vdev bus first and then all bus
for all device, calling rte_dev_remove.
