A fabric controller can sometimes send an RDP request right before a link
down event. Because of this outstanding RDP request, the driver does not
remove the last reference count on its ndlp causing a potential leak of RPI
resources when devloss tmo fires.
In lpfc_cmpl_els_rsp(), modify the NPIV clause to always allow the
lpfc_drop_node() routine to execute when not registered with SCSI
transport.
This relaxes the contraint that an NPIV ndlp must be in a specific state in
order to call lpfc_drop node. Logic is revised such that the
lpfc_drop_node() routine is always called to ensure the last ndlp decrement
occurs.
