[SCSI] libfc: make rport module maintain the rport list
The list of remote ports (struct fc_rport_priv) has been
maintained by the discovery module. In preparation for having
lport->tt.rport_create() do a lookup first, maintain the
rports list in the rport module. It will still be protected
by the disc_mutex.
The DNS rport is an exception for until after further patches.
For now, do not add it to the list.
The point-to-point rport will be in the discovery list.
So at shutdown, it doesn't need to be separately logged out.
