qla2x00t-32gbit: Fix NVMe and NPIV connect issue

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
