The next patch will create poll group threads dynamically for NVMe-oF target, and will need to wait for completion of poll group and I/O channel destroy. This is a preparation for the next patch. Add callback function and its argument to spdk_nvmf_poll_group_destroy(), and to struct spdk_nvmf_poll_group, respectively. The callback has not only cb_arg but also status as its parameters even if the next patch always sets the status to zero. The reason is to follow spdk_nvmf_tgt_destroy's callback and to process any case that the status is nonzero in future. spdk_nvmf_poll_group_destroy() sets the passed callback to the passed poll group. Then spdk_nvmf_tgt_destroy_poll_group() calls the held callback in the end. This change will ensure all pollers are being unregistered and all I/O channels are being released.
