scsi: lpfc: Transition to NPR state upon LOGO cmpl if link down or aborted

Browse Source 
In P2P topology, a target controller reboot sometimes results in not
reestablishing a login because the ndlp is stuck in LOGO state.

Fix by transitioning to NPR state if we get link down before LOGO
completes.
