[SCSI] fc_transport: stop creating duplicate rport entries.

Current fc_transport consumers initially register rports
with an UNKNOWN role-state and follow-up with a call to
fc_remote_port_rolechg().  Modify code in
fc_remote_port_add() to scan the fc_host_rport_bindings()
array for consistent bindings regardless of role-type.
Original code would only scan bindings array for targets,
causing duplicate fc_remote_ports/rport-X:Y-Z entries to be
created for the yet-to-be-role-changed rports.
