PCI: pci-stub: ignore zero-length id parameters

pci-stub uses strsep() to separate list of ids and generates a warning
message when it fails to parse an id.  However, not specifying the
parameter results in ids set to an empty string.  strsep() happily
returns the empty string as the first token and thus triggers the
warning message spuriously.

Make the tokner ignore zero length ids.
