Justin Tee b5c18c9dd1 scsi: lpfc: Fix unsolicited FLOGI kref imbalance when in direct attached topology 
In direct attached topology, certain target vendors that are quick to issue
FLOGI followed by a cable pull for more than dev_loss_tmo may result in a
kref imbalance for the remote port ndlp object.

Add an nlp_get when the defer_flogi_acc flag is set.  This is expected to
balance the nlp_put in the defer_flogi_acc clause in the
lpfc_issue_els_flogi() routine.  Because we need to retain the ndlp ptr,
reorganize all of the defer_flogi_acc information into one
lpfc_defer_flogi_acc struct.
