Subject: [PATCH 163/217] cxl/port: Relax port identifier validation

Now that util_cxl_port_filter() accepts port host identifiers it is no
longer possible to pre-validate that the port arguments follow the "port%d"
format. Instead, let all inputs through and warn if the filter fails to
identify a port.
