scsi: lpfc: Handle duplicate D_IDs in ndlp search-by D_ID routine
After a port swap between separate fabrics, there may be multiple nodes in
the vport's fc_nodes list with the same fabric well known address.
Duplication is temporary and eventually resolves itself after dev_loss_tmo
expires, but nameserver queries may still occur before dev_loss_tmo. This
possibly results in returning stale fabric ndlp objects. Fix by adding an
nlp_state check to ensure the ndlp search routine returns the correct newer
allocated ndlp fabric object.
