Remove the early return NLP_FABRIC check in lpfc_plogi_confirm_nport
because it is possible for switch domain controllers to change WWPN.
As a result, allow lpfc_plogi_confirm_nport to detect that a new ndlp
should be initialized in such cases. The old ndlp object will be cleaned
up when dev_loss_tmo callbk executes.
