Subject: scsi: lpfc: Fix SLI3 hba in loop mode not discovering devices
Patch-mainline: v5.5-rc1
Git-commit: feff8b3d84d3d9570f893b4d83e5eab6693d6a52
References: bsc#1154521

When operating in private loop mode, PLOGI exchanges are racing and
the driver tries to abort it's PLOGI. But the PLOGI abort ends up
terminating the login with the other end causing the other end to
abort its PLOGI as well. Discovery never fully completes.

Fix by disabling the PLOGI abort when private loop and letting the
state machine play out.
