scsi: lpfc: Fix non-recovery of remote ports following an unsolicited LOGO
A commit introduced formal regstration of all Fabric nodes to the SCSI
transport as well as REG/UNREG RPI mailbox requests. The commit introduced
the NLP_RELEASE_RPI flag for rports set in the lpfc_cmpl_els_logo_acc()
routine to help clean up the RPIs. This new code caused the driver to
release the RPI value used for the remote port and marked the RPI invalid.
When the driver later attempted to re-login, it would use the invalid RPI
and the adapter rejected the PLOGI request. As no login occurred, the
devloss timer on the rport expired and connectivity was lost.
This patch corrects the code by removing the snippet that requests the rpi
to be unregistered. This change only occurs on a node that is already
marked to be rediscovered. This puts the code back to its original
behavior, preserving the already-assigned rpi value (registered or not)
which can be used on the re-login attempts.
