scsi: lpfc: Ensure HBA_SETUP flag is used only for SLI4 in dev_loss_tmo_callbk

[ Upstream commit 1cced577 ]

For SLI3, the HBA_SETUP flag is never set so the lpfc_dev_loss_tmo_callbk
always early returns.  Add a phba->sli_rev check for SLI4 mode so that
the SLI3 path can flow through the original dev_loss_tmo worker thread
design to lpfc_dev_loss_tmo_handler instead of early return.
