hw/nvme: Expand VI/VQ resource to uint32

VI and VQ resources cover queue resources in each VFs in SR-IOV.
Current maximum I/O queue pair size is 0xffff, we can expand them to
cover the full number of I/O queue pairs.

This patch also fixed Identify Secondary Controller List overflow due to
expand of number of secondary controllers.
