Fix regression from PR #680

Browse Source 
Hi @ollyg! Unfortunately I have found some issues with the code we
finally released in #680:

* get_port_macs expects an array ref but values() returns array,
  so the code was never called due to the return unless... check
* When fw_mac_list had exactly two entries, only the second value
  was bound as a scalar to the parameter. This is probably due
  to the shorthand bind formats described in
  https://metacpan.org/pod/DBIx::Class::ResultSet#DBIC-BIND-VALUES,
  but I'm not a 100% on this.
* return unless now checks for an entry in the list, with the old
  check the statement was also executed for empty lists

In cases where only the device(_port)?.mac lookup worked for uplink
detection, users of 02.044005 - 010 might get a lot of uplinks not
labeled as such.
