> - Are the (below) devices bound to vfio-pci or any other kmod at this point of the init?

Yes, vfio-pci is bound to 0030:01:00.0 in the log.

> - Is the spdk_nvme driver loaded at this point?

No, spdk just attempts to initialize dpdk at this point.
After the initialization finishes, spdk probes the nvme driver.

> - I suppose forcing --iova-mode=pa resolves the issue, but can you confirm this?

Yes, you are right. I needed to modify the spdk core to do this, anyway..
Here is the log when I specify --iova-mode=pa for an example app of spdk (identify)
