[SCSI] libfc: change interface for rport_create

The interface for lport->tt.rport_create() takes a fc_disc_port arg,
which is unnatural for most calls.   The only reason for this was
to avoid passing in the local port as an argument, but otherwise
added to complexity.

Simplify by just using lport and fc_rport_identifiers.
