scsi: lpfc: Treat IOERR_SLI_DOWN I/O completion status the same as pci offline

During receipt of a hardware error attention ACQE, IOERR_SLI_DOWN status is
set by the driver for all outstanding I/Os.

In such hardware error attention cases, we can treat the situation exactly
the same as pci_channel_offline.  Thus, add IOERR_SLI_DOWN status to the
same category as pci_channel_offline handling in lpfc_nvme_io_cmd_cmpl.
