In the autotest, when calling kill_stub() function, there is error log
like this: "Device 0000:83:00.0 is still attached at shutdown!", so it's
better to detach the controller when exit the stub process.
But after call spdk_nvme_detach() in the stub process, there is another issue:
1. NVMe stub running as the primary process, and it will send 4 AERs.
2. Using NVMe reset tool as the secondary process.
When doing NVMe reset from the secondary process, it will abort all the
outstanding requests, so for the 4 AERs from the primary process, the 4
requests will be added to the active_proc->active_reqs list.
When calling spdk_nvme_detach() to detach a controller, there is a
assertion in the nvme_ctrlr_free_processes() at last to check the
active requests list of this active process data structure.
We can add a check before destructing the controller to poll the
completion queue, so that the active requests list can be flushed.
