[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.
