scsi: lpfc: Fix crash involving race between FLOGI timeout and devloss handler
When a FLOGI completes with a sequence timeout error, a freed kref ptr
dereference crash can occur due to a timing race involving ndlp referencing
in lpfc_dev_loss_tmo_callbk.
Fix by ensuring the driver accounts for an outstanding FLOGI when dev_loss
is active. Also, don't remove the HBA_FLOGI_OUTSTANDING flag when the
FLOGI is retried to allow the driver to handle the reference counts
correctly in lpfc_dev_loss_tmo_handler.
