For non-fabric controllers, the corresponding I/O qpairs are simply
re-enabled at controller reset.
This had a issue when I/O qpairs span multiple threads and poll group
is used.
spdk_nvme_ctrlr_reconnect_poll_async() calls
nvme_transport_ctrlr_connect_qpair() with qpair->async being false.
Then nvme_transport_ctrlr_connect_qpair() calls
spdk_nvme_poll_group_process_completions() until the qpair is connected.
spdk_nvme_poll_group_process_completions() may poll other qpairs.
This may cause I/O to complete on a wrong thread.
For PCIe controller, spdk_nvme_poll_group_process_completions() calls
spdk_nvme_qpair_process_completions() simply for each qpair.
Hence change nvme_transport_ctrlr_connect_qpair() to call
spdk_nvme_qpair_process_completions() if the controller is non-fabrics.
