scsi: lpfc: Fix PT2PT PRLI reject

[ Upstream commit a71e3cdcfce4880a4578915e110e3eaed1659765 ]

lpfc cannot establish connection with targets that send PRLI in P2P
configurations.

If lpfc rejects a PRLI that is sent from a target the target will not
resend and will reject the PRLI send from the initiator.

[mkp: applied by hand]
