This is another preparation to disconnect qpair asynchronously. Add nvme_qpair object and move the qpair and poll_group pointers and the io_path_list list from nvme_ctrlr_channel to nvme_qpair. nvme_qpair is allocated dynamically when creating nvme_ctrlr_channel, and nvme_ctrlr_channel points to nvme_qpair. We want to keep the times of references at I/O path. Change nvme_io_path to point nvme_qpair instead of nvme_ctrlr_channel, and add nvme_ctrlr_channel pointer to nvme_qpair. nvme_ctrlr_channel may be freed earlier than nvme_qpair. nvme_poll_group lists nvme_qpair instead of nvme_ctrlr_channel and nvme_qpair has a pointer to nvme_ctrlr. By using the nvme_ctrlr pointer of the nvme_qpair, a helper function nvme_ctrlr_channel_get_ctrlr() is not necessary any more. Remove it.
