scsi: lpfc: Fix PT2PT PRLI reject (reapply patch)

[backport of 114e80db15039e248eb4e458559cef57737930a8]
From: rkennedy <dick.kennedy@avagotech.com>

Orabug: 29281346

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.

[tv: original mistakenly applied in reverse, because change was already
present in the code at that point; this reapplies forwards]
