scsi: lpfc: Allow support for BB credit recovery in point-to-point topology 



Currently, BB credit recovery is excluded to fabric topology mode.  This
patch allows setting of BB_SC_N in PLOGIs and PLOGI_ACCs when in
point-to-point mode so that BB credit recovery can operate in
point-to-point topology as well.
