NVME controller fails to send connect command due to failure to locate
hw context buffer for NVME queue 0 (blk_mq_hw_ctx, hctx_idx=0). The cause
of the issue is NPIV host did not initialize the vha->irq_offset field.
This field is given to blk-mq (blk_mq_pci_map_queues) to help locate
the beginning of IO Queues which in turn help locate NVME queue 0.

Initialize this field to allow NVME to work properly with NPIV host.

 kernel: nvme nvme5: Connect command failed, errno: -18
 kernel: nvme nvme5: qid 0: secure concatenation is not supported
 kernel: nvme nvme5: NVME-FC{5}: create_assoc failed, assoc_id 2e9100 ret 401
 kernel: nvme nvme5: NVME-FC{5}: reset: Reconnect attempt failed (401)
 kernel: nvme nvme5: NVME-FC{5}: Reconnect attempt in 2 seconds
