scsi: qla2xxx: Fix NVMe and NPIV connect issue
commit 4812b7796c144f63a1094f79a5eb8fbdad8d7ebc upstream.
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.
