The lldd rebinds the ndlp with rport during a nvme rport registration
(va nvme_fc_register_remoteport). If rport & ndlp pointers are same as
the previous one, the lldd will re-use the ndlp and rport association
without re-iniitalization. This assumption is incorrect. The lldd should
be ignorant of whether the returned rport pointer is new or not, and
should always assume it is new.
Remove the re-binding code, always assumes that rport pointer received
from transport is a new pointer.
