scsi: lpfc: Ensure PLOGI_ACC is sent prior to PRLI in Point to Point topology

Browse source

[ Upstream commit 2bf81856a4 ]

There is a timing race condition when a PRLI may be sent on the wire
before PLOGI_ACC in Point to Point topology.  Fix by deferring REG_RPI
mbox completion handling to after PLOGI_ACC's CQE completion.  Because
the discovery state machine only sends PRLI after REG_RPI mbox
completion, PRLI is now guaranteed to be sent after PLOGI_ACC.
