A clean up log message is output from lpfc_els_flush_cmd for each
outstanding ELS I/O and repeated for every NPIV instance. The log message
should only be generated for active I/Os matching the NPIV vport. Thus,
move the vport check to before logging the message.

Fix smatch warning regarding missed calls to free_irq. Free the phba irq
in the failed pci_irq_vector cases.

With repeated port swaps between separate fabrics, there can be multiple
registrations for fabric well known address 0xfffffe. This can cause ndlp
reference confusion due to the usage of a single ndlp ptr that stores the
rport object in fc_rport struct private storage during transport
registration. Subsequent registrations update the ndlp->rport field with
the newer rport, so when transport layer triggers dev_loss_tmo for the
earlier registered rport the ndlp->rport private storage is referencing the
newer rport instead of the older rport in dev_loss_tmo callbk.
Because the older ndlp->rport object is already cleaned up elsewhere in
driver code during the time of fabric swap, check that the rport provided
in dev_loss_tmo callbk actually matches the rport stored in the LLDD's
ndlp->rport field. Otherwise, skip dev_loss_tmo work on a stale rport.

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.
